I' ll try to apply this commit to our package and provide an update hopefully tonight.

I have submitted mate-user-share-1.6.1-1.1.mga4 to core/updates_testing repository. This update include upstream patch which should fix your issue. Please test it if the issue resolves.

Thanks! I will test it in the next few days.

I have uploaded a patched package for Mageia 4.

Suggested advisory:
========================

Updated mate-user-share package fixes a critical crashing bug:

Before updated package, mate-user-share tries to use ~/Downloads folder for incoming bluetooth files altough mate-bluetooth is deprecated and doesn't included in repositories. So, without mate-bluetooth installed it crashes caja.

This update includes an upstream patch to fix this critical bug.

Were you able to test the updated package Nathan?

Have just tried this and caja still crashes on ~/Downloads.

And I can confirm that installing mate-bluetooth prevents the crash.  Will remove mate-bluetooth and await further developments.

Attila, are there any logs we can watch to help with debugging?

Just found this in dmesg:

[170233.769058] caja[22942]: segfault at 9 ip 00007fc5ebb285b9 sp 00007fff0cb93130 error 4 in libgobject-2.0.so.0.3800.2[7fc5ebaf6000+4e000]
[170350.002778] caja[22995]: segfault at 9 ip 00007f15213295b9 sp 00007fff44f68570 error 4 in libgobject-2.0.so.0.3800.2[7f15212f7000+4e000]

Sorry about taking so long to test this! Thanks for the reminder!

With and without mate-bluetooth installed, it's not crashing for me. After installing mate-user-share-1.6.1-1.1.mga4 (x86_64), I restarted the X server and logged back into mate. Opening the ~/Downloads directory didn't crash caja. mate-bluetooth was not installed (gnome-bluetooth is, though I don't know if that makes a difference; I didn't want to uninstall it because I sometimes play around with gnome).

I did install mate-bluetooth after that initial test just to see if it made a difference. Opening ~/Downloads still doesn't crash caja (not that it ever did).


Since I'm not seeing a problem with the test package, but Len is, could some other package be interferring? Except for this one mate-user-share package, I'm running standard Mageia 4, fully updated.

Now it does not crash for me either.  I had not thought to restart the X server.

Hi, indeed user should logout and log back in to the desktop to unload/load mate-user-share. Since, all you said that the main problem is fixed (?) then please validate. Thank you for testing this update. :)

Thanks for confirming Atilla.

Two confirmations so validating. 
Advisory uploaded.

Please push to 4 updates

Thanks
