Comment 1 fanzhuyifan 2024-03-02 19:04:49 UTC 
Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git master, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #10 0x0000713a1719bd05 in ??? () at /usr/lib/libkateprivate.so.24.02.0

Could you please install debug symbols and attach a new symbolicated backtrace generated by using coredumpctl gdb in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this.


Thanks again!

Here is the output: https://pastebin.com/S9kezGjh
It might be the rust LSP that's crashing Kate, but I'm not sure. I opened different source files and I don't get any crashes.

Please type `bt` in the gdb prompt and copy the output.

Comment 6 Waqar Ahmed 2024-03-18 11:50:32 UTC 
Not entirely sure about this because the backtrace is incomplete, but most likely https://invent.kde.org/utilities/kate/-/merge_requests/1426 will fix this
Comment 7 Waqar Ahmed 2024-03-18 19:01:22 UTC 
Should be fixed in the next release, if not, reopen the bug.
