Exception not cought and error message not overly helpful.

When an exception occurs we should catch that and provide a clean error response.
The error response should always tell you the user which file was being attempted to be copied so that the user knows what needs to be redone.

The exception below is an example of the sort that needs catching:

ERROR:: (u'Error parsing capabilities document.', XMLSyntaxError(None,))

@andamian if I fix this bug will you do a code review?
