Comment 3 for bug 413168

Thanks for sticking with this. If it is still an issue, you're right - it's obviously not a duplicate. I'm unmarking as such.

There appears to be a broken idletimer within x. Your bug may be related to this. Hopefully this will be fixed soon with merges, otherwise we'll need to get these fixes into x.
