Tracking 49/50+ for this regression, especially since it was not addressed by the bug in Comment 0.

--> Removing state about this being a regression from bug 1141468, since this is now marked as a dupe of a bug that itself is marked as a regression from bug 1141468.  (If we leave both bugs marked as "blocking" bug 1141468, then it makes it look like bug 1141468 caused more independent regressions than it actually did, when looking at it's dependency list.)
