Comment 3 TraceyC 2024-12-10 17:28:07 UTC
Backtrace looks like it's all in Qt
Comment 4 TraceyC 2024-12-10 17:44:24 UTC
Based on the backtrace it seems to be the same crash as bug 496048. I'm marking this as a duplicate of that one. As noted in the other report, this is a bug in Qt that is fixed in 6.8.2. The crash should no longer happen on your system when Qt is updated to that version.
