13275	url_backwards_re catastrophic backtracking (?) problem	Karen Tracey	Chris Beaven	As noted here: http://code.djangoproject.com/ticket/12945#comment:20 the new url_backwards_re appears to hang in some circumstances. When we've seen this before it has been due to catastrophic backtracking, so I'm guessing that's the cause here, though I can't say with complete certainty that that is the the issue.		closed	Template system	dev		fixed		Brian Neal Łukasz Rekucki perrygeo	Ready for checkin	1	0	0	0	0	0
