If the issue isn't supposedly with the running system, please keep
in mind that if the developers are the same in the testcases, odds are
more than likely it's either a) library code, or b) copy-pasted code
(hopefully it's not the latter case, but there's a large amount of
code like that in the tree).
I know it's not extremely helpful at first glance, but that's the
usual case if you can get a fix to work with one testcase, and others
need fixing...
