I was testing bug 60816 by creating a post with bad HTML. When I clicked Preview the errorbox shows only An unexpected error occurred. clicking Reply gives a more helpful An error occurred. The error message received was: Exception Caught: ID searchbox already defined So exception reporting is inconsistent between preview and reply. I would lean towards providing more information. The particular exception from bug 60816 should be fixed by 1.23wmf13, after that you'll have to find a different post error to reproduce this bug.
The frontend-rewrite changes how this works, so closing this as INVALID.
