KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
Wireless connection seemed to stop working, in an attempt to fix, I ran "sudo restart network-manager"  which resulted in a crash.

syslog does seems to indicate that the actual service shut down and started up gracefully.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
