Description Kurt Wilson 2024-09-18 04:41:34 UTC

Application: plasmashell (6.1.5)

Qt Version: 6.7.2
Frameworks Version: 6.6.0
Operating System: Linux 6.10.10-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.1.5 [CoredumpBackend]

-- Information about the crash:
Application specific details: I'm using UPPAAL 4.1.20. When running a statistical query, it shows the result in (what I think is a) JOptionPane. If I run multiple queries together, UPPAAL shows these dialogs in sucession - acknowleging all of them causes a plasmashell crash.

UPPAAL is closed source, so I can't 100% confirm the mechanism causing the crash, but give me a few days and I'll try to reproduce it in Java.

The crash can be reproduced sometimes.

I'm using the Doom effect from Burn My Windows, but the bug occurs with the stock Fade effect too

Thank you for the bug report! This seems to be the same crash as bug 488596, which was recently fixed in the current development version. The fix should be included in Plasma 6.2, to be released in early October.
