I cannot reproduce this failure locally, however this test looks like it suffers from the same issue that plagued other tests, see bug 211079 and bug 210156. Will try to use the same approach for this test and see if this addresses the issue.

Comment on attachment 401034 [details] Patch I assume that this patch didn't actually manage to break everything, including the webkitperl tests, as EWS seems to say.
