Bug 358072

Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-300.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
In the network drop up in tray icon menu I was connected to one wifi network and clicked on connect for another network.

Because of https://bugs.kde.org/show_bug.cgi?id=354292 I did not search for dups (grml)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
