I think I found a bug in Python 2.6.4 (in the inspect module)

No, that wasn't the case. The argument of inspect.getargvalues() is a 
'frame object' not 'function object'.

e.g.:
 >>> inspect.getargvalues(inspect.currentframe())

You could argue that the error message is misleading (should be 
TypeError instead), do you want a bug report on that?
