Bug 488759

Application: baloo_file_extractor (6.3.0)

Qt Version: 6.7.1
Frameworks Version: 6.3.0
Operating System: Linux 6.9.5-arch1-1 x86_64
Windowing System: X11
Distribution: Arch Linux
DrKonqi: 6.0.5 [CoredumpBackend]

-- Information about the crash:
Happened once just after rebooting, happened once randomly while surfing the web. Basically, I get a popup saying that the Baloo File Extractor has crashed. Since it's happened twice in the same day, I figured I would generate a backtrace and report it. No other unusual desktop behavior noticed. No other error popped up on the desktop when telling it to restart the app, either.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Aborted
