It was exactly that: Exception thrown without a stack frame in Unknown 
on line 0

The redirect is done on the actual server side.
Nginx has a rewrite rule checking for missing trailing slashes and 
redirecting them.
Since there is already a known port in that case, it redirects to 
domain.com:12345/typo3/

Yes it did, since in this case server name and port matched the incoming 
values, I guess.
