Unfortunately your backtrace is missing debug symbols, making it hard to tell what's going on. Can you please install debug symbols and upload a new backtrace?
(In reply to Nicolas Fella from comment #3) > Unfortunately your backtrace is missing debug symbols, making it hard to > tell what's going on. > > Can you please install debug symbols and upload a new backtrace? I will try but I am not sure if this will reporduce. I had similar crash today but the result was less severe, everyghing still worked after the "Report bug" window poped, just one window flickered. Will try to upload as is and later will try to add debug symbols.
Created attachment 167020 [details] kcrash data from possible reproduction.
It's hard to tell because of the lack of debug symbols, but it crashes somewhere in KService. This might be specific to NixOS's way of doing things
Very likely dupe of 484807, the backtrace looks similar to me. But it also could be related to nix. If you can repro the backtrace with debug symbols, you can send it here. *** This bug has been marked as a duplicate of bug 484807 ***
