getting a ktp-contactlist crash when trying to open the joinchatroom dialog.

Happens with
OpenSuse 13.1 with Distribution: KDE:Extra / KDE_Current_openSUSE_13.1dr
Name        : ktp-contact-list
Version     : 0.8.80

Name        : ktp-contact-list
Architecture: x86_64
Signature   : DSA/SHA1, Do 18 Sep 2014 14:47:30 CEST, Key ID 27c070176f88bb2f
Source RPM  : ktp-contact-list-0.8.80-20.2.src.rpm
Build Date  : Do 18 Sep 2014 14:47:17 CEST

Appears after the update to OpenSuse 13.1 (before I was using 12.3 with current
KDE stable release)
A typical backtrace:

gdb ktp-contactlist

Reproducible: Always

Steps to Reproduce:
1. start ktp-contactlist (either on the command line or via the menue)
2. press the "join groupchat" button (it is a visual '#')
(Does not depend on if I am offline or online.)

Actual Results:  
crash

Expected Results:  
Join Groupchat dialog opens.

I guess some old configuration setup causes the issue to appear.
I have two accounts configured, but there used to be favourite rooms
before the upgrade when I've opened the dialog. They are not there.
Looking for them in .local shows that there is no config file.
