If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?
Thanks!

Comment 3 Justin Zobel 2024-10-08 22:28:43 UTC

Could you please install debug symbols and attach a new symbolicated backtrace. In the backtrace you're missing Qt and Calligra debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Arch_Linux about using debuginfod to get the symbols required.

Comment 4 Rune 2024-10-10 12:20:05 UTC

This here is all that I can get:

Using host libthread_db library "/usr/lib/libthread_db.so.1".
Core was generated by `/usr/bin/calligrasheets'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x000076285eca23db in pthread_kill () from /usr/lib/libc.so.6
[Current thread is 1 (Thread 0x762856fe0ec0 (LWP 4633))]

It seems that Arch Linux does not provide debug symbols for calligrasheets. Is there another way for me to help?

Comment 5 Rune 2024-10-10 19:30:08 UTC

I installed Fedora 40 in a QEMU VM and got the backtrace.
