Comment 1

[Josh Matthews [:jdm]]

Blake/Bobby, this warning is a bit worrisome.

Comment 2

[Bobby Holley (:bholley)]

Probably a regression from bug 718543. I will look into it.

Any progress?
Or could the failing test be disabled in the meantime?

Comment 4

[Bobby Holley (:bholley)]

I'll hopefully have time to look at it later this week. If this is happening a lot, the best interim solution is probably to back out bug 718543.

SeaMonkey bug 728790 is perma-orange:
bug 718543 backout would be appreciated, as a confirmation and to get time to fix.

Backed out: http://hg.mozilla.org/mozilla-central/rev/75fcd465d506

Serge, can you verify that this fixes the SM perma-orange?

It didn't :-/ (Though this very bug is fixed on SM too ;-))
