(In reply to Geoff Brown [:gbrown] from comment #0) > Like bug 974306? bug comment 0 failed at the start of the test, rather than on a later invocation of the HomePager (i.e. [1]). Both end up on the HomePanel of index 0 (i.e. HISTORY). It could be related, but I don't have any clues as to the cause.
