This is very strange. On you site, /cgit?r=fsmenu works as expected,
while /cgit?url=fsmenu does not, and instead shows a path-filtered
repolist (url=fsmenu is how $PATH_INFO is handled internally).
When specifying r=fsmenu, "fsmenu" is passed as argument to
cgit_get_repoinfo() [1], and when specifying url=fsmenu, "fsmenu" is
passed as argument to cgit_parse_url() [2], which in turn invokes
cgit_get_repoinfo() [3] on its argument. This should Just Work.
If you could add a fprintf() to cgit_get_repoinfo() [4], like this
fprintf(stderr, "cgit_get_repoinfo(%s)\n", url);
and report back what you get in your webserver logfiles when accessing
/cgit/fsmenu
/cgit?r=fsmenu
/cgit?url=fsmenu
That might help us pin down the cause of the problem.

Thanks for the feedback. I've added the patch (pasted that as the first
line of the function), recompiled and discovered that Lighty doesn't use
the error log but redirects to STDOUT :). Anyway, results:
"/cgit/fsmenu"
cgit_get_repoinfo(fsmenu)
"/cgit/fsmenu/"
cgit_get_repoinfo(fsmenu/)
cgit_get_repoinfo(fsmenu)
"/cgit?r=fsmenu"
cgit_get_repoinfo(fsmenu)
"/cgit?url=fsmenu"
cgit_get_repoinfo(fsmenu)
The server is Ubuntu 10.04 x64, and I've tried compiling cgit on my
desktop which is 10.10 x64 against a fresh tarball of Git v1.7.3.5,
still the same result (where I ran the above tests actually). Perhaps
try an Ubuntu x64 virtual machine using something like KVM or VirtualBox
and see if you can spot the issue too? All my packages are from the
standard repos.

Even more strange (I was hoping to see some munging of query params
due to url rewriting or some such). But with identical input, you
should get identical output (ctx->repo should point at the correct
repo-struct in all the above cases), so I assume that ctx->repo
somehow becomes NULL after the call to cgit_get_repoinfo(), but only
when initialized via cgit_parse_url().
Could you try running cgit under gdb to find the culprit? E.g:
$ PATH_INFO=fsmenu gdb ./cgit
(gdb) break cgit_parse_url
(gdb) run

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>

Good to hear (even though the cause of the problem remains a mystery).
