I added this line recently. The crash is basically completely non-deterministic,
and I had one case, where it just failed instead of crashing.

I talked to florian schneider about it. This test should be removed or skipped
as it is now -- it provides no value. I replied on the bug.

It was consistently crashing on the bots for the last 100+ revisions.
