-- Information about the crash:
The crash happened during "normal" webbrowser use, unfortunately I can't give a better description. At least the backtrace contains debug symbols. I'm typing this blindly, because drkonqi is slightly broken as well in this Wayland session it seems. ;)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Falkon (falkon), signal: Aborted
