I inbstalled trac in multiproject configuration, using c:/trac as root dir and hanging several project below it.
I also installed Trac Hours as time tracker, and after some minor issues everything went ok.
The only report not working is multiproject report, the project list appears empty and hence none is shown as time consumed.
I checked environment variables and works fine. My fast exploration into code gave me no clue aboou what it is going on, except that apparenty track hourse uses "get project from url" method or similar.
By the way I attach the piece of apache configuration for mod_python and trac environment:
<Location />

</Location>
<Location /css>
