If it doesn't happen with "Aquamacs -Q", there must be a configuration
which results in that effect. Could you try to test with "Aquamacs -Q",
and add the smallest configuration snippet which provokes the error? We
could analyze then that configuration.

Unfortunately, those backtraces don't tell something which would explain
the problem.
