[otrs] Debian: Internal Server Error

[otrs@otrs.org]

Hello!

I've been trying to get the system to work on a Debian GNU/Linux Woody
(stable) installation, but so far, it fails me on one thing. 

The entire installation went flawless. After the installation I can
modify, close, zoom tickets. I can add users, delete them: the lot.

However: I cannot add a ticket! :-) 

Clicking on 'PhoneView' brings up the 'Phone call / new ticket' page.
After filling in the form and pressing 'store', I get a 500 error from
my Apache.

This happens on 2 different machines. As far as I can tell, all required
perl-modules have been installed. I get a 'Syntax OK' when performing
'perl -cw path/to/bin/cgi-bin/index.pl'. Nothing shows in the
(error)logs either.

The same problem occurs with the 'customer.pl' script.

Does anyone have any idea how I go about debugging this? 

Thanks!
