Application: plasmashell ()

Qt Version: 5.4.0
Operating System: Linux 3.19.0-8-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I diconnected the cable, but the network manager didn't recognize the wired connection had been diconnected. The crash happened, after I had connected to WiFi.
Note: I faced a problem with KDE walled. Writing password was faced with error 9, even though the passord is correct.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
