In general, it would be helpful if you could attach the (stripped-down) source file with which you could reproduce the error. Here however, it's most probably a dup of bug 72583. Please reopen if you can reproduce with a build >= I200409231635. *** This bug has been marked as a duplicate of 72583 ***
It seems OK with the 3.1M2 version.
