Please describe the problem:
Launchers whose Type is set to Link do not launch local paths like "/home/foo".
 They need "file:///home/foo".

However, when one clicks "Browse" and selects a file, the local filename is put
into the URL box without the file:// prefix.  Then, if the launcher is clicked,
the error "The specified location is invalid" is given.

Note that nautilus doesn't have this problem - it considers the URL without the
file:// to be valid and launches the local location correctly.

So:
 - The browse button should set the URL string correctly, including the file://
prefix
 - When it doesn't have a :// prefix, the launching code should assume it's
seeing a local path and act accordingly.

Does this happen every time?
