Googling around suggests that this python error is often due to a .pyc
file becoming corrupted.
If you are on a RPM based system you could perhaps try "rpm
-qf /usr/lib64/python2.4/site-packages/xen/web/httpserver.py*" and see
if that reports any corruption (A 5 in the third column indicates the
md5 sum has changed).
In that case reinstalling the relevant RPM and/or remove httpserver.pyc
(it will be automatically regenerated) ought to help. You may also want
to check your disks for failures and/or report the issue to your distro
(or Xen .rpm provider) in case there is a packaging or python
infrastructure issue.
