Description Vitaliy Gorbunov 2011-02-06 19:02:46 UTC 
Version:           4.6 (using KDE 4.6.0) 
OS:                Linux

At least 2 times per day all kde apps suddenly crashes, so I can see only black screen and non-kde apps. DrKonqi try to start and also crashes. I can't even run Alt+F2. 
Restarting kdm give no effect.

dmesg:
//Here is crash
plasma-desktop[5988]: segfault at 0 ip           (null) sp 00007fff01e68ea0 error 14 in kdeinit4[400000+c000]
//Here I try to call Alt+F2
krunner[6001]: segfault at 7fff01e69500 ip 00007fff01e69500 sp 00007fff01e69230 error 15
//And trying to restart kdm
fuse init (API version 7.15)
plasma-desktop[6204]: segfault at 0 ip           (null) sp 00007fff672a24b0 error 14 in kdeinit4[400000+c000]

So I have to reboot my OS.

It reminds me https://bugs.kde.org/show_bug.cgi?id=259472. But as I know libsolid-upnp wasn't included in KDE SC 4.6 and symptoms was quite different, so I guess it's not duplicate. 


Reproducible: Sometimes

Happened again...
Please tell me how I can provide more information without Drkonqi, or at least how to fix it without rebooting.
Comment 2 Vitaliy Gorbunov 2011-03-05 14:22:36 UTC 
When I remove smooth-tasks plasmoid it happens not so often, but still exist.
And in Kde 4.6.1 it happens again.
