Bug 352612

Application: plasmashell (5.4.90)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.1.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I created a Jabber / KDETalk.net account (I tried doing it both ways), then attempted to connect to it. This failed (for SSL or authentication issues). So I opened the Instant Messenger Settings dialogue again from the Instant Messaging plasmoid, and pressed "configure" for the account. This caused Plasma to crash.

Deleting and re-creating the account seems to be the only way I can edit it.

The crash can be reproduced every time.

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