HOWTO: Make a launcher restore an open window (dock-like)

Also, Thunar isn't working with launch-restore. Using the script causes it to open a window (and multiple instances thereof). On a hunch I ran wmctrl -lx and I noticed the output for the Thunar window was this:

0x03800003  0 <unknown>.<unknown>   jon jon - File Manager

Just running Thunar alone (via the terminal) wmctrl reports that window correctly (thunar.Thunar).

Edit: I tried "tricking" it by using -n 'File Manager' and got this debug output:

['0x03800003', '0', '<unknown>.<unknown>', 'jon', 'jon - File Manager\n']

Edit2: Tried Gaim for the heck of it (partially the reason I wanted to be able to handle multiple windows ) and got this output:
