Operating System: KDE Linux 2026-02-03 KDE Plasma Version: 6.6.80 KDE Frameworks Version: 6.23.0 Qt Version: 6.10.2 Kernel Version: 6.18.7-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics Memory: 17 GB of RAM (16.0 GB usable) Graphics Processor: AMD Radeon 780M Graphics I was testing a merge request (https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/3516). I compiled it and restarted plasma. plasmashell crashed and DrKonqi opened a crash report window, but it immediately displayed two error banners (see attached screenshot).

The unknown reasons it that you live updated your files and now drkonqi Unexpectedly stumbled over a deleted mapping: 0x7f8e44359000+0x5d000 a1058bf92a8487947708f32ade708396b698d5ed@0x7f8e443592f8 - - /lib/libkglobalaccelmodel.so.6.6.80 (deleted)
That's just now to test merge requests, though. Did I do something wrong?
Not wrong per se. drkonqi cannot trace a crash that has a deleted mapping because we have no way of knowing if the new file on disk is same-ish enough to the old file to have the trace make sense. It's a guard rail to prevent reporting crashes with nonsense frames or crashes that were caused by doing a live update. That said, a manually invoked gdb will still happily trace things, it just may end up saying the crash involved frame foo when in fact it involved bar (because the two changed places in the new binary)
