KDE apps crash on KDE exit (logout/poweroff/restart)

[Gustaw Smolarczyk]

Binary package hint: kdebase

I am using Lucid packages. I cannot assign this bug report to any package because many of them crashes and I do not know why exactly.

A lot of KDE applications (I cannot say exactly how many) crash when I exit from KDE (issue shutdown, restart or logout). There are a lot of DrKonqi's windows, but I cannot read what backtraces they contain because session ends after a few seconds. Additionally some applications restart, like Plasma.

I could provide more information about the crash if I knew the way to read them. This crash happens every time.

Maybe it could be also related to my video driver change (from fglrx to OSS r600 driver).

I managed to get some backtraces. The first is from plasma. It is related to katesessions applet, so I removed it. The second crash report happened when I try to remove the applet. After removal one crash is gone.
There are some crashes left - one related to KNetworkManager. I am going to try to track them down.

This is really probably because of Qt 4.6. KDE 4.3.x was never tested with Qt 4.6 as it was intended to be used with Qt 4.5 since 4.6 was in beta at the time. Things should resolve themselves once the KDE 4.4 betas hit Lucid. If not, please direct all KDE application crashes to bugs.kde.org. Thanks.
