CGIT not working with PATH_INFO under Ubuntu 10.04 / Lighttpd

I'm not running any URL rewriting on my CGIT instance except for setting
the index page for the subdomain to "/cgit".

Output from GDB at a console:

GNU gdb (GDB) 7.2-ubuntu
...
This GDB was configured as "x86_64-linux-gnu".
...
(gdb) break cgit_parse_url
Breakpoint 1 at 0x4080fc: file parsing.c, line 22.
(gdb) run
Starting program: /pathname/cgit 
[Thread debugging using libthread_db enabled]

Breakpoint 1, cgit_parse_url (url=0x6ca030 "fsmenu") at parsing.c:22
22	parsing.c: No such file or directory.
	in parsing.c
(gdb) 

If run normally, it generates a page with the main index logo/header
and:

<div class='content'><table summary='repository list' class='list
nowrap'></table><div class='error'>No repositories found</div>
</div>
