Application: kded4 ($Id$)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
Laptop restarted from sleep.  Network was non-functional.  Neither ethernet or wireless was valid. /etc/resolv.conf had been wiped.  Network manager claimed at various times that the ether was connected or the wireless was connected, but then refused to do anything with them.  Restarted network-manager to clear up the confusion, got segfault.

- Unusual behavior I noticed:

Laptop using both wired and wireless links.  VPN active to remote site.  resolv.conf altered to use remote DNS.  Logins hung after system restart.  No response in network manager plasma panel.

The crash can be reproduced some of the time.

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