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

Quite often when I start Kontact I receive a crash notification on my desktop. In some cases there is no new window and I need to relaunch Kontact to use it and in some cases Kontact window still show up after crash notification and I can use it as normal. It seems like akkregator session is in all cases crashed and needs to be restored or dismissed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
