Mhhh, I searched around for an idea about this problem, but it looks odd...

Would you try to replace the file: testman4trac/trunk/testmanager/macros.py

with the attached one: http://trac-hacks.org/attachment/ticket/8154/macros.py?format=raw

build (with ". ./build.sh") and replace the test manager plugin, and let me know if it works?

Another thing you may try is to follow the instructions in this post: http://bugs.python.org/issue6501

they require some Apache tweacking.

Ciao, Roberto
