Note that it really *should* only be bugs that cause that sort of error - if there is something that shouldn't cause it to happen then please do raise a JIRA with details, so we can tighten the error trapping and reporting (so we know if it is a real bug or someting we need to report more clearly that can be rectified by the user - without a stack trace being necessary of course !). Thanks, Michael.
