Comment 39 for bug 1300557

Jeroen T. Vermeulen, just to advise, you asking follow up questions doesn't make this less Incomplete, or more Confirmed. Until this is bisected, it's most difficult for a developer to attend to this, let alone have this Triaged and upstreamed.

Despite this, I want to confirm you have read the entire bisect article in its entirety, as it contains answers to questions like this.
