[Bug 849414] Re: plymouthd crashed with SIGSEGV in ply_event_loop_process_pending_events()

[James Hunt]

Please could anyone who can reproduce this problem attach
/var/log/boot.log (which will always exist), ideally along with /var/log
/plymouth-debug.log as suggested by @vorlon.

@brian: I've raised bug 860371 for apport to do this automatically.

Also, it would be interesting to know if the problem only happens at
early boot. If anyone would care to try triggering the problem "post-
boot", that might provide us with some useful information:
