It holds the complete location for the file which is being transferred.
And this means that it hold the directory where, in your case, the file will
be uploaded before there is any file.
You could simply use getValue() from the file element instead of changing
the base implementation.
Please keep in mind that Zend_File_Transfer was not designed to work only
with HTTP uploads!
Forcing it to do so is no solution except that it negotates downloading and
other protocols like ftp, webdav and so on, which are actually in
development.
