Description Exceptions Reporter 2012-09-03 06:29:31 UTC 
This bug was originally marked as duplicate of bug 185330, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

The preceding exception in the log seems to be the culprit:

Comment 3 Tomas Pavek 2012-09-03 17:14:23 UTC 
Looks like the problem described in bug 127881. Should be verified and marked as duplicate of that bug.
Comment 4 Quality Engineering 2015-02-04 03:27:33 UTC 
Reported for 7.3.x or earlier, no new info since then -> closing as worksforme, please reopen in case you see it.
