Comment 44 for bug 515386

Hi,
i have the same problem with raring.
for me there seem to be at least 2 errors in the script:
in open_gnome the wrong variable is used to find the desktop file (browser instead of desktop)
and in desktop_file_to_binary() the grep command finds multiple occurences of 'Exec'. The supposed patch below only takes the first one and removes all following lines.

hence i suppose the following changes, that seem to work for me:
