Comment 1 Harald Sitter 2025-03-02 18:32:59 UTC

Can you fetch the console output for us? It might include debug information that should tell us what is going on here.

I can reproduce a crash, when using a slow connection to the KNS servers, but the backtrace is different.

Comment 2 Kosimas 2025-03-04 17:55:53 UTC

After an Aurora update I can't reproduce the error anymore. On my Arch system I never had this error. I think this report can be closed.
