[Python.NET] python for net with python 2.6

All, We have been trying to use python for net compiled against python26 with a target framework of 2.0 and are getting a hard crash. .NET Runtime version 2.0.50727.4927 - Fatal Execution Engine Error (719D851A) (80131506) We are able to "import clr", "import System", but when you do something as basic as "s = System.String('a')" you get a hard crash. These commands were run from the pythonw.exe from the python26 directory. Your assistance in this matter would be greatly appreciated. Thanks
