Bug 467653

Application: falkon (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.104.0
Operating System: Linux 5.19.0-35-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.3 [KCrashBackend]

-- Information about the crash:
Selecting the menu option to open a file crashes the program. Seems to be related to the file picker, as the crash also happens when trying to open or save a file on Okular, Gwenview, Kate and Krita, among others.

The crash can be reproduced every time.

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