[jQuery] Problems w. IE7

[jQuery] Problems w. IE7

Im trying to use the minimized version on a site im developing. It works like a charm in FF/Chrom/IE8+ but when i try to run it in  IE7 it gives me:
      Error: Invalid argument.

If i run the debugger it breaks on 
  1.  if((!r||-1===b.inArray(o,r))&&a=b.contains(o.ownerDocument,o),s=Ot(f.appendChild(o),"script"),a&&Mt(s),n))
With the message:
      htmlfile: Invalid argument.

Does this make sense to anyone? Anyone have an idea if how to fix it?

Regards
