URL/URI problem [Solved]

[eluser]Queops[/eluser]
Hello everyone.

I got a controller called main, that has a function:

Code:

function test($name)
    {
        echo $name;
    }

As simple as this.
Now, I have my fancy URL's but if I go to example.com/main/test/FileName-_-Whatever_Strng-Here_0.0.1.zip,
what shows up is:

FileName-_-Whatever_Strng-Here_0_0_1_zip

Which means it converts the dots to underscores.. but I have no clue why. My uri permitted chars are as default (which means .'s are allowed).

EDIT: I also talked to people on IRC channel, some guy tried this out and told me works fine for him. So I suspect it's Apache or PHP related.

So.. what could it be?
