Bug 313297

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.97
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic i686
Distribution: Ubuntu 12.10

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

I was trying to reactivate a wired connection after waking my laptop from suspend to RAM.  I was clicking in every part of the knetworkmanager applet to try to fniod a solution.

- Unusual behavior I noticed:

My wired network did not come back after resume as it usually does.  The cause may be that I had to kill and restart kded4 previously  during the same KDE session because it was using too much RAM (memory leak).  In the process of trying to find a solution to my network problem I also restarted networkmanager at the system level.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
