Bug 311213

Application: kded4 ($Id$)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.7.20121204c x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

Turning dnsmasq back on in the /etc/NetworkManager/NetworkManager.conf configuratoin, then ran "restart network-manager" while connected to wired, wireless, and VPN connections. one of the kdeinit processes then segfaulted.  This didn't happen during the first restart, when I disabled dnsmasq in network manager.

I haven't retried reproducing the issue yet.

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