[web2py] Invalid request if the URL contains a special char or umlaut

[Dan]

Hi,

I'm using the lates Version of Web2py and getting a invalid request if
I'm using any special chars like %21 (!) or umlauts. Web2py is running
with the fcgihandler and Lighttpd. All special chars are encoded by
using urllib.quote().

Please help!

Thanks a lot.
