strace on zoom
The strace output of running zoom (or rather /opt/zoom/zoom.sh, the debugging script for zoom with an strace added after the library environment has been set)
I also have the coredump if anyone is interested, or could find it useful. Let me know and I will download it as well.
Try the workaround described at https://wiki.mageia.org/en/Using_Zoom_communication_application#Update:_2020_11_14 CC:

mageia Nice discovery, Martin; and usual thanks for same. Does it not also imply 'use an earlier version'? "Update: 2020_11_14 More recent versions of the zoom download RPM will crash silently. For example: zoom-5.4.53391.1108-1_x86_64.rpm will crash but the older zoom-5.3.472687.1012-1_x86_64.rpm will run OK." But we must await the complainent's feedback, because what he preposes re pulseaudio might yet be a factor. CC:

lewyssmith It seems the PulseAudio thing was just a coincidence. Putting in unset QT_PLUGIN_PATH="" got rid of the crash, and the program opened. It did not get rid of the tearing/flickering on Sharing on guests, but that is another bug. Putting in the unset seems easy enough so that you can enjoy the bug fixes that Zoom put into the new version. And since the Qt devolopers explicitly state that QT_PLUGIN_PATH should NOT be set globally, Mageia's doing so and breaking Zoom is on Mageia's head. The other problem is that it seems to be inpossible to regress Zoom. They ONLY put up the latest version, and AFAIK you cannot get older versions. Always save a copy of the RPM when installing it. Then you can revert to a previously saved copy. Sure. And I happened to do that, but I suspect it is not common. And just one user having his Zoom destroyed because of Mageia's mistake is too many (Bug 25038). It has now been over a year that it has been pointed out that the Qt Developeres specifically warn that distributions should NOT set QT_PLUGIN_PATH globally, and Mageia still does it. Since we have all come to rely on zoom to work and stay sane, it is really time that the bug was fixed. The chances of someone who has lost all access to zoom finding the kludge to fix it (either in this bug list or in the mageia wiki) are not terribly high. Do you happen to know whether this applies to Mageia 8 also? I have no wish to install Zoom to find out... > Putting in unset QT_PLUGIN_PATH="" got rid of the crash > It has now been over a year that it has been pointed out that the Qt > Developeres specifically warn that distributions should NOT set > QT_PLUGIN_PATH globally, and Mageia still does it Despite the explicit advice given in the Wiki cited in comment 2, this is not the first time we have had a bug due to this. It looks a valid point. The maintenance of Qt4|5 is unclear, so assigning this bug globally if only for an opinion. CC'ing NicolasL as the official man. CC:

mageia I have not tried Mga8 to see if it suffers from the same problem, but if you just look to see if QT_PLUGIN_PATH is defined (env|grep QT will show it) that should be sufficient to see if the bug is still there. And that does not require installing Zoom. Note that one does not need to unset QT_PLUGIN_PATH, one can just set it to nothing export QT_PLUGIN_PATH='' will also work. I have a bug report in to Zoom about this and they are looking at it. Whether that will result in action, I do not know. If a bad QT_PLUGIN_PATH can crash zoom, they really should reset it themselves. But if Mageia is the only distro with this problem, then the pressure on them is dissipated. It seems to be set in /etc/profile.d/60qt5.sh It may be that something in the drak tools is set up to assume that it is defined, expecially the /usr/lib64/qt5/plugins/kcms part. Looking through the lib and bin directories there are a few things with use it but nothing in the drak libs. >sudo grep -r QT_PLUGIN_PATH /lib* Binary file /lib64/libKF5CoreAddons.so.5.57.0 matches Binary file /lib64/libdigikamcore.so.6.1.0 matches Binary file /lib64/libdigikamcore.so.5.9.0 matches /lib64/qt5/mkspecs/features/qt_functions.prf: pluginpath.name = QT_PLUGIN_PATH Binary file /lib64/libKF5kipiplugins.so.5.9.1 matches Binary file /lib64/libQt5Core.so.5.12.6 matches Binary file /lib64/libQtCore.so.4.8.7 matches >sudo grep -r QT_PLUGIN_PATH /usr/libexec/ Binary file /usr/libexec/kf5/kioslave matches Re Mageia 8, yes, it is still set: QT_PLUGIN_PATH=/usr/lib64/qt5/plugins:/usr/lib64/qt5/plugins/kcms: ------------ As for Zoom, I think you could reasonably ask them, not a bug, rather than only offer their latest version, but also to retain & offer earlier versions for download; explicitly to cover cases like this where the latest version introduces a problem.

ouaurelien The problem was that QT_PLUGIN_PATH was set in /etc/profile.d/60qt5.sh Checking my Mageia 8, it is not set in that file. You (Lewis) could check to see if it is being set there as some sort of hangover from you old Mga7, or check to see if qtbase5-common-5.15.2-4.2.mga8 package is installed and that it did not leave the old 7 version active. Ie, it does seem that the bug is fixed in Mga8 Checking my Mageia 8 system, under LxQt: - QT_PLUGIN_PATH does not seem to exist (hence, is not set). - qtbase5-common-5.15.2-4.2.mga8 is the only such named RPM, no mga7 version. Just for confirmation. |
