Comment 3 for bug 254278

I'm getting this at the moment, I'm running two instances of bzr in the same apache/mod_wsgi container - the smart server for anon access and the track bzr plugin.

If I start apache and access the smart server first, that works fine but the trac instance fails, but if I access trac first then the smart server fails, both with the "AttributeError: 'module' object has no attribute 'ElementTree'" error.

So it sounds like the import-fu at the top of bzrlib/xml_serializer.py is failing when run twice? Is that even possible?

Attaching the stack from the logs.
