The Submit result-form is broken

[DrSwizz]

I have submitted a few result today and yesterday. Every single time I get got the following reply from the server:

 

Your browser sent a request that this server could not understand.

Request header field is missing ':' separator.

The "garbage charcters above being random (I guess the server has converted a binary object to text?)

 

When I go back to the form and fill out the missing pieces and submit the result again the form does work and my result is accepted.

I have not attempemted to input any strange characters or anything into any of the fields.

 

I am using Iceweasel 3.0.6 (rebranded Firefox webbrowser).

I tried submitting a few results using FF 3.6.6 and everything seemed to work just fine.
