Any clues what might be causing it?

Fix for failing tests under Python 2.5

Change History

comment:1 Changed 12 years ago by chrisz

I have examined this problem a little deeper and found it is caused by the fact that exceptions in Python 2.5 are new-style classes, so a comparison with InstanceType? in controller.py falls through. I have attached a patch to the current 1.0 branch after which all tests run thorugh in Python 2.4 and 2.5.
