Created attachment 50811 [details] New crash information added by DrKonqi plasma-desktop (0.3) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.6.3 - What I was doing when the application crashed: I used shutdown and turn off and during the logout it crashed. -- Backtrace (Reduced): #7 0x00007f49cd264656 in ComicApplet::~ComicApplet (this=0xa72b50, __in_chrg=<value optimized out>) at /usr/src/debug/kdeplasma-addons-4.5.0/applets/comic/comic.cpp:208 #8 0x00007f49e0f5532f in qDeleteAll<QList<Plasma::Applet*>::const_iterator> (end=<value optimized out>, begin=<value optimized out>) at /usr/include/QtCore/qalgorithms.h:322 #9 qDeleteAll<QList<Plasma::Applet*> > (end=<value optimized out>, begin=<value optimized out>) at /usr/include/QtCore/qalgorithms.h:330 #10 ~ContainmentPrivate (end=<value optimized out>, begin=<value optimized out>) at /usr/src/debug/kdelibs-4.5.0/plasma/private/containment_p.h:65 #11 Plasma::Containment::~Containment (end=<value optimized out>, begin=<value optimized out>) at /usr/src/debug/kdelibs-4.5.0/plasma/containment.cpp:156
I have no clue what this could be, has anyone more knowledge on this and is any 4.5 system effected with the comic applet in usage?

I am still not able to reproduce this issue. Can you reproduce it with 4.6.3?
Hi, I have no more problems with the above mentioned issue (currently in 4.6.3). fli.
