This issue does not occur after 20130630. Must have been fixed since there were a couple of failures prior to this image. Marking it fix released.

[Para Siva (psivaa)]

Hmm no, I am not marking it anything leaving it as it is for the informed :)

[Brian Murray (brian-murray)]

Since this has not been encountered again I am setting it to Fix Released.
