Matt, Is this a general scenario? What is your take on the user impact of this bug. If you can help us with investigating this so we can decide whether to track that would be great.

I suspect this is a dupe, or at least very similar to bug 936792.

It doesn't need to track, as OMTC for windows is only enabled for nightly builds.
