Do you think the crash could be reproduced at will again ? Thanks I just added the kget icon back, and yes it has crashed again. When I get some more time I'll try to fiddle a bit more with it to narrow it down more. Here is the end of the backtrace: Application: Konqueror (kdeinit4), signal: Aborted [KCrash Handler] #5 0x00007f7ed6174645 in raise () from /lib/libc.so.6 #6 0x00007f7ed6175b63 in abort () from /lib/libc.so.6 #7 0x00007f7ed98b6765 in qt_message_output () from /usr/lib64/qt4/libQtCore.so.4 #8 0x00007f7ed98b6890 in qFatal () from /usr/lib64/qt4/libQtCore.so.4 #9 0x00007f7ed98e0636 in QListData::realloc () from /usr/lib64/qt4/libQtCore.so.4 #10 0x00007f7ed98e085d in QListData::append () from /usr/lib64/qt4/libQtCore.so.4 #11 0x00007f7ed6def025 in ??

() from /usr/lib64/libkdeinit4_konqueror.so The second backtrace seems to be a bit different. Stange enough both backtraces seem to be pure Qt4 functions. Do you know if Gentoo patches Qt4 ? Also, the last backtrace shows one function from Konqueror (you may need to recompile kdebase/apps with debugsymbols enabled in order to get a completer backtrace; but now I don't know if you would be able to reproduce again) Thanks Gentoo probably does patch Qt4, but I doubt significantly enough to cause problems. I just tried again, and I couldnt get the Download Manager icon to make it crash again. The 'About KDE' one did it though. #5 0x00007fef2f069fa9 in ??

possible patch
A solution would be to decouple the use of the action from its effect.
This patch fixes it for me, at least in konqueror.
SVN commit 1013099 by dfaure: Use queued connection in order to fix crash when editing toolbars; the xmlgui-rebuilding was deleting the menuitem that called this slot in the first place, and this is a nice and easy way to decouple the two things. Will backport for 4.3.1. BUG: 200815 M +9 -6 kstandardaction.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1013099 *** Bug 203252 has been marked as a duplicate of this bug. *** |
