For now, 

I have tested the following scenarios: 

- 4 nodes
- stonith-enabled=true
- no-quorum-policy=stop

AND

- 2 nodes only
- stonith-enabled=true
- no-quorum-policy=ignore

I ran the test case (bug description) for hours and could not get a crash, although I do get the following messages (expected) from time to time:

Depending on Peter to get his crash + core dump for the analysis.
