Created attachment 85707 [details] New crash information added by DrKonqi plasma-desktop (4.11.5) on KDE Platform 4.11.5 using Qt 4.8.5 - What I was doing when the application crashed: Logging in from KDM with theme starboard after a hard system crash (had to restart with the power-button - cutting the power). - Unusual behavior I noticed: plasma-desktop crashes with segfault. Notes: - I am currently rebuilding every package on my system to see whether this fixes it. - plasma-netbook still works. - I run a PyQt4 UniqueApplication which also dies with a segmentation fault since the crash (pyrad: http://draketo.de/light/english/pyrad ). -- Backtrace (Reduced): #6 0x00007f8dd8d98eef in Plasma::loadEngine(QString const&, Plasma::ComponentType, QObject*) () from /usr/lib64/libplasma.so.3 #7 0x00007f8dd8d994b6 in Plasma::loadScriptEngine(QString const&, Plasma::Applet*) () from /usr/lib64/libplasma.so.3 #8 0x00007f8dd8cedebd in Plasma::AppletPrivate::init(QString const&) () from /usr/lib64/libplasma.so.3 #9 0x00007f8dd8cf3011 in Plasma::Applet::Applet(QObject*, QList<QVariant> const&) () from /usr/lib64/libplasma.so.3 #10 0x00007f8dd8d40f4e in Plasma::PopupApplet::PopupApplet(QObject*, QList<QVariant> const&) () from /usr/lib64/libplasma.so.3
Note: Rebuilding PyQt4 did not fix the issue.
[I am a GCI student] Change name to include QMetaObject::cast ().
Both of you: please disable the plasma applets done with Python, this has been a problem since quite some time now
Plasma 4 is obsolete. Closing my own report.
