Saving file bug?

Question

sometimes I am noticing that when saving a file, if I define
the file inside a function it gets what seems to be a bug.
I have this code:
var newFile:File =
File.desktopDirectory.resolvePath("tab_icons/myimage.png");
which results in saving this on my desktop:
C:\Documents and Settings\jisaacks\Desktop\function
Function() {}\tab_icons\myimage.png\function Function() {}
its seems it is adding
\function Function() {} before and after the string I pass.
if I define the file in the begening of the code outside the
function there is no problem.
the app I am noticing this in is pretty complex, when I tried
to simulate the same thing by creating a new blank file and just
making a function to define the file and save it, it did not
produce the bug so I am not sure exactly what in my code is making
this happen. I can post my entire code if requested.

Answer 1

ok I have pinpointed the problem to this function:
Array.prototype.in_array = function( what ) {
for( var a = 0; a < this.length; a++ ) {
if( this[a] == what ) {
return true;
else if( this[a] is Array ) {
return this[a].in_array( what );
return false;
this function has nothing to do with saving files, but
whenever I remove this function and any calls to it, I no longer
have a problem, I wonder if there is something in here that messes
with the built in code?
