Thanks for the bug report Seo.  We've had a similar bug in our database that I believe I fixed last week (I'm away currently so I can't verify) but I will confirm this next week after the Thanksgiving holiday and let you know if it'll be present in our next release.

Subject: [IronPython] Crash on method call

With following code, IronPython 0.9.5 crashes with the message
"Unhandled Exception: no value for arg".

class C:
    def foo(self, arg, bar):

obj = C()
obj.foo(None, bar=1)

Above testcase was reduced from Python standard library's optparse.py,
line 1120, in Python 2.4.2.
