Arch Linux

Rebuilding doesn't produce any code changes.

Then I'm guessing I should ask upstream the issue to be reopened? Any other suggestions on how to find the source of the problem?

Rebuild tracker3-miners with debug symbols according to https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces and get a backtrace from coredumpctl after the next crash.

Is this still happen? Did you report it to upstream again?
