Please install debug symbols and create a new backtrace.

Here's a stack trace with kcm_systemd debug symbols. This is the best I can do.

I've only been able to reproduce this once since yesterday. I shut down the service by right click - Stop Unit, then right clicked again triggered the segmentation fault. But it's working since then. Maybe this bug is not worth investigating.
