I think moritz's point about SELinux is a good one. So, you might first want to check whether it's enabled (cat /etc/selinux/config — IIRC that's the respective config file). In case it's enabled, you could temporarily disable it (though I think that would require a server reboot...), to see whether the problem goes away.

If all else fails, you could start Apache in debugging mode (option -X — in which case it will start only one child/worker), attach strace to that process (via option -p, as root), and then make the request. The strace output should give you a clue as to what's wrong...
