See bug 730039 comment 32. Hopefully whatever patch lands for that bug will fix this one as well.
Depends on: 730039
Actually, I don't think the patch in bug 730039 will fix this, but TabsAdapter.mTabs is suffering from the same problem that we found with Tabs.mOrder. We need to implement a more threadsafe solution in TabsTray.
There don't appear to be any new crashes since bug 730039, so I believe that patch fixed this crash.
