<pre>Curiously enough, I'm able to reproduce this same crash when running the layout tests with a patch I'm testing. The patch itself is not relevant, but the fact that the crash is reproducible even with the XErrorTrapper is curious. BTW, the crash is only reproducible when running several parallel tests. Running the failing tests alone they don't crash.
17:00:27.204 41276 The program with pid 37321 received an X Window System error.
17:00:27.204 41276 The error was 'BadDamage (invalid Damage parameter)'.
