Application: kopete (1.13.0)
 (Compiled from sources)
Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.15.18-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

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

As soon as I connect to a xmpp connection kopete segfaults. 
I can see that it manages to get the roaster before crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: Kopete (kopete), signal: Segmentation fault
