Description Leonid Zhaldybin 2012-03-22 20:05:58 UTC
Application: kded4 ($Id$)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.0-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
On my Fedora 17 installation, kded4 process crashes every time I turn off the wifi adapter by hardware switch. The active wifi connection is not necessary, turning the adapter on and then off again is enough to reproduce the problem.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
