Comment 1

[Daniel Veditz [:dveditz]]

If confirmed this would be potentially critical.

Comment 3

[Christian Holler (:decoder)]

I cannot reproduce this on trunk but the trace looks like the one in bug 738985. That bug should be fixed though even on beta and aurora.

Abhishek: What revision of beta/aurora did you use? The fix for that other bug landed at April 10. Can you reproduce with beta/aurora tip now?

Comment 4

[Abhishek Arya]

I found it on- 
aurora - beef2cc3afb0
beta - 6323a689d6f1
, but it does seem fixed now. I just tested-
aurora, tip - 01ae9ced59c6
Beta, tip - 0ba53003ae26
