I'm having the same problem with a mandrake 10.0 client - the error message which says that "list objects are unhashable". It sounds like you have an idea what the problem is; I just want to say I have the problem too. Is there a way I can repair this? Any idea when a patch might be released? I'm new with yum; we've been using OSCAR on our cluster but changing to warewulf/yum to manage our own installations. I would appreciate any help you can offer and I am willing to test things or whatever might be needed. We're in a hurry (as usual) so I'll help in any way I can.
