Mod_python error: "PythonHandler mod_python.publisher"

SyntaxError: invalid syntax
Mind: I run this out of the main python script, though psp.PSP and then
page.run(). That may make a difference as well! I haven't tested it
as .psp page, which won't work as that way I can not pass the search
results to teh page.
