It only crashes with a socket, e.g. "systemctl status sshd.socket", even
without tab-completion. The log message is:

A manual bisect revealed it happens since commit 916abb "socket: add
POSIX mqueue support". My core dump doesn't have any symbol names at
all.

Another symptome to mention is that when it occurs, it changes from X to
the console.

HTH,
