ISSUES

1. [New issue] rrule.rulestr()
http://ironpython.codeplex.com/workitem/33114
User gharig has proposed the issue:

"I receive an 'write to closed file' exception when executing a sample console vb.net application.  I'm trying to use a dateutil rrule.rulestr() function.  Works fine until I add the keyword 'UNTIL' to the string.  I set the path for pyEngine.GetSearchPaths() to "C:\Python27\Lib" and "C:\Python27\Lib\site-packages\dateutil"

The error seems to be thrown in a call to Pythons parser.py class _timelex(object):

Thank You
George
