It's not a bug that it doesn't restart. Many services don't do so.
Respawning a dying daemon is not a good idea, because in case of
exploitation of a security issues, it would effectively defeat
randomization giving the attacker more tries, etc. etc.

The real problem is the crash. Do you have a core dump? Or at least
relevant lines from the log file? Are you able to reproduce the problem?
Please do file a bug in case you do/are.

This is the following bug:
https://bugzilla.redhat.com/show_bug.cgi?id=299131
I somehow had to delete that directory manually also, though I don't
remember the actual setting anymore. Probably it is derived from $USER
rather than from the effective id and gets created when you start the
daemon as another user or whatever. It is also a (though pretty low
severity) denial of service condition.
