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

one day starting akregator locked up X entirely, requiring a hard restart. Since then akregator reliably crashes on startup with the following backtrace.

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
