Description of problem:
I think this was because I drag and dropped a service onto the node it was
already thought to be running on, but I can't be for sure because I only was
able to reproduce this a few times.

Traceback (most recent call last):
  File "/usr/share/system-config-cluster/MgmtTab.py", line 318, in
