Hi, Felix.

I also got Redirect Loop error. bbPress keeps redirecting me to the same tag page as it compares decoded actual uri string and non-decoded should-be string.

$bb->debug = 1 will show the actual- and should-be- request URLs for the tag page, instead of redirecting former to the latter.

This trouble is issued as a difect at https://trac.bbpress.org/ticket/585 , which I may have mixed up.
