Uhm. It seems that the old bug of not delivering http with mod_ftp loaded

Ghost is possibly working in trunk without doing the make clean; make
I mentioned?
I did ./configure.apxs; make clean; make ...
Did it again, just to be sure.
Discovered now that I got a bunch of coredumps, will get back to you if I
find something useful...
This is httpd 2.2.6, worker MPM, compiled with -g and with optimization,
on Ubuntu 7.10 32bit, mod_ftp trunk r610730.
Backtrace of cores looks like this:

I guess that following a NULL pointer didn't work this time either ;)
I haven't looked closer at the code, but it seems to me that
something is broken. Should it even try to insert an ftp filter for
non-ftp connections?
