Your patch truncates any string value at the first %.  I don't think
that's the right way to go.

The comments at the top of the source file read as follows:

  * We will only deal with Type == "Application" entries in [Desktop
  * Entry] groups. Since there is no passing of file name arguments or
  * anything of the sort to applications from the menu, execname is
  * determined as follows:
  * - If `TryExec' is present, use that;
  * - else use `Exec' with any switches stripped

Clearly this is not what the code actually does.  The quick hack would
be to change xdg_to_wm() to truncate the command-line at the first
instance of white-space (which is what is done to derive (*wm)->Name
from (*xdg)->Exec or (*xdg)->TryExec); the right thing to do would be to
implement the FDO quoting rules first:


Doesn't look too hard.  I'll put something together.
