Version information nor available for older mod_python

[tjb@…]

After updating our trac installation to changeset:6378, trac ceased to work for us. The apache log showed a mod_python error, along the lines of:

ImportError: Cannot import name version

Our environment is Suse Enterprise Linux 9, Apache 2.0.49, mod_python 3.1.3

Looking for help with mod_python shows that 'version' is only available form mod_python 3.2

I have reverted to a previous trac version (r6372), and all is OK.

A quick, simple fix (ignoring details about older versions):

trac/web/modpython_frontend.py

Ok for the suggested fix. The important thing here is that we know whether people are using the recommended version (3.3.1) or an older one.

(oh, and I think it's better if it would be except ImportError: instead of just except:)

Replying to cboos:

Good point. Added and applied in [6382].
