Bug 352730

Application: plasma-desktop (4.11.13)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.2 (jessie)

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

I had just restarted NetworkManager (thru systemd)

- Unusual behavior I noticed:

Prior to this, the network management plasmoid had been acting oddly, not allowing me to untick the "wireless enabled" checkbox.

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