Ok, I think I fixed it.  Basically I think my apache directives were
confusing it.  My original directives were:
-------------------------
Alias /trac/ /usr/share/trac/htdocs/
<Directory "/usr/share/trac/htdocs">
 Options Indexes MultiViews
 AllowOverride None
 Order allow,deny
 Allow from all
</Directory>

<Location /trac>
   SetHandler mod_python
   PythonHandler trac.ModPythonHandler
   PythonOption TracUriRoot "/trac"
   PythonOption TracEnvParentDir /path/to/trac/
</Location>
-------------------------
Notice how there is an Alias directive for /trac, but also a Location
directive.  If I change the Location and TracUriRoot to something
slightly different, everything seems to magically work:
-------------------------
<Location /tracsrv>
...
   PythonOption TracUriRoot "/tracsrv"
...
</Location>
