Version:            (using KDE 4.0.83)
Installed from:    Ubuntu Packages
OS:                Linux

After Login KDE 4 started with an akregator-icon in system section in control bar. I didn't remember leaving kontact running at my last shut down, but I'm sure I didn't use the akregator-plugin during the whole last session.

So I tried to quit kontact with this icon. Right click (the number of unread messages was updated), and choose quit. Nothing happened a longer time. Then kontact notify a SIGSEGV (level 11).

Regards.

PS: Backtrace:

Application: Kontact (kontact), signal SIGSEGV
