Thanks for logs, they revealed the reason for the crash.
Apparently, if network partitions in certain point of group negotiation, one of the partitioned component may form a group with invalid group id, which in turn causes group ids of partitioned components to be identical. Crash happens when network connectivity returns and group tries to remerge.
