TRAC_ENV necessary ...

[rupert thurner]

we have multiple trac instances and set the environment with mod python in apache like:

PythonOption TracEnvParentDir /var/trac-parentdir

this leads to the error:

This error is caused by not setting your master_path. It should give a better error since the last changeset.
