trace caught by drakbug

(top of trace is just SIGV handler catching the segfault and forking drakbug)

Seen 3 times.
I do not know yet how to reproduce it.

Severity: normal => enhancement

Please test new oxygen rpm.

i just encountered this bug today but i don't know how to reproduce and how to get a good gdb trace

If it was reproductable, we could attach gdb but...

I suspect some thread issue (that would explain the hard to reproduce part). 
Possibly the crash occurs when a new widget is created (the "realizeHook" is triggered by the "realize" signal of a widget. 
So maybe when a popup is about to be shown ?
 
For the record, using mageia 1, here (and lots of code manually compiled, but not mageia core code), I never had such crash. So I can't even start to try helping (unless if installing cauldron)

GDB trace with symbols

Totally reproductible on up to date cauldron with gtk+2.0-2.24.10-3.mga2 and oxygen-gtk-1.2.1-2.mga2

Start a GNOME session with Oxygen.
Use gnome-tweak-tools to switch back to Adwaita.
Net_applet & mgaapplet both segfaults immediately

Working on it (still), since I can (likely) reproduce using gtk-chtheme.
See: https://bugs.kde.org/show_bug.cgi?id=275366
(the diagnostic is somewhat different but I believe the issue is related).

Will keep you posted.

Can someone give a shot to oxygen-gtk2-1.2.2 
(http://download.kde.org/download.php?url=stable/oxygen-gtk2/1.2.2/src/oxygen-gtk2-1.2.2.tar.bz2)

and/or oxygen-gtk3-1.0.2
(http://download.kde.org/download.php?url=stable/oxygen-gtk3/1.0.2/src/oxygen-gtk3-1.0.2.tar.bz2)

Problems may (or may not) have been fixed in these releases
(at least I tried).

Thanks,

Hugo

It get better with the new oxygen-gtk packages (tested in Gnome): no segfault
in mgaapplet and net_applet, but after switching back from oxygen-gtk the theme
doesn't revert cleanly (a log out and log in is needed). Thanks Hugo, hope you
will succeed to find a fix for this glitch as well.

Hi,

This bug was filed against cauldron, but we do not have cauldron at the moment.

Please report whether this bug is still valid for Mageia 2.

Thanks :)

Cheers,
marja

You will have cauldron pretty soon :)
