6170	Reverse urlresolver raises obscure exceptions on failure	abrahamson.j@…	nobody	"Related to ticket #2977.

When {{{reverse}}} fails to reverse a complex regex obscure errors can be raised. For instance, reversing the url {{{r'^(\d(\d)?)/$'}}} causes an 'unbalanced parenthesis' to be raised from {{{re.py._compile}}}.

The urlresolver is clearly in flux right now; however, this error could be very difficult for someone new to Django (read, me) to understand. Better exception catching that notifies when a url isn't supported by {{{reverse}}} would be very helpful."
