XSV and Python 2.5

Is there an issue running XSV, the Schema validator, with Python 2.5?

When I run 

  python commandLine.py foo.xsd

I get a backtrace that ends with

  File "/usr/lib/python2.5/site-packages/XSV/compile/SSchema.py", line 205, in initFromDump
    raise errorI 
  XSV.compile.SSchema.error: "shouldn't happen"

The error occurs whether the Schema file is valid or complete nonsense.

I set PYTHONPATH to the directory containing XSV; that's under python-2.5/site-packages on 
my Fedora 10 box.

Any help appreciated.
