<pre>I'm using systemd --user rather heavily to manage my processes. Since I updated
from 208 to 210 on Arch Linux, I experience sporadic segfaults on the user
instance, which I can't reproduce for now, only wait for it to happen again.
>From a coredump and an unstripped binary compiled a posteriory, I managed get a
partial stack trace, which I attach below. I'm not certain why there is still
missing debug data...
Is there anything else I can get from that coredump?
