[PATCH] Fix qb on lighttpd (=Fix my blog)

[Uli]

I just noticed that on my blog, no matter what you click, you always get to the
front page which means *every* *single* *link* to some article was broken.

With some echo debugging I found out that $_SERVER['PATH_INFO'] is set, but
empty. Yay for lighttpd.

And no, I don't know nor do I care since when this is broken. But if you find it
out, tell me :).
