https://bugzilla.suse.com/show_bug.cgi?id=1173750 https://bugzilla.suse.com/show_bug.cgi?id=1173750#c3 --- Comment #3 from Mathias Homann <Mathias.Homann@opensuse.org> --- (In reply to Matthias Gerstner from comment #2)

1) what are the exact steps to trigger the crash (supposedly `systemctl start usbguard`?)

exactly. i start usbguard with systemctl, and when I check its status afterwards I find it has crashed enough times for systemd to give up on it.

2) what component exactly is crashing? The usbguard-daemon?

yep.

3) a backtrace of the core dump would be helpful. Try installing usbguard-debuginfo, glibc-debuginfo, systemd-coredump and gdb. Then trigger the crash and run `coredumpctl attach`. You should end up in gdb shell. Enter `bt` and paste the backtrace here in this bug.

Thank you.
