If you leave off the trailing slash, apache doesn't know whether you
want a file called "erhverv" in the docroot, or a subdirectory. So it
issues a redirect to http://www.domain.dk/erhverv/. But how does it get
the servername? It uses the ServerName directive - if that is missing
(as in your case) it uses the IP address hence the client gets the wrong
URL when the request following the redirect comes in. 

In other words:

Client: http://www.domain.dk/erhverv

Server: Sorry, don't have file like that, but I do have a directory.
I'll make you a redirect... Oh dear, no ServerName. Never mind, I'll use
the IP address. OK client, try http://192.168.1.1/erhverv/

Client: http://192.168.1.1/erhverv/

Server: Hmmm. No ServerName in this request - I'll just go to the first
VirtualHost then... Yikes! No file called erhverv! - oh well: 404....

Read the Docs about ServerName and UseCanonicalName to understand what's
going on.
