Comment 9 for bug 496113

I'll leave this open as triaged in case someone else has a similar problem, the info I need can be found using the tweaks I posted.

As to why it should suddenly start working after inserting a couple of print statements, well that has me baffled (if you are brave you could remove those statements and see if it breaks again, that would really be odd).

Glad it's working for you now.
