[ClusterLabs] Corosync ifdown / ifup crash with Assertion `token_memb_entries >= 1' failed.

[Alexander T]

Hello everyone!

I was wondering if the project is aware of the bug at
https://bugzilla.redhat.com/show_bug.cgi?id=989934 and if it has been fixed
in recent releases.

It leaves pacemaker in a half-crashed state and it was non-trivial to track
down in my case. If anyone could explain how this error occurs it would be
beneficial for me, since I need to explain to a customer the reason why
ifdown/up isn't working (and is unsupported).

The traceback in my case is:
