Comment 3 for bug 16966

I tried that. It doesn't seem to work at all.

I am assuming that the %U has to be at the end of the command in the current
.desktop file logic.

Additionally, it will break spaces and other escape characters.

Actually I thought about this a real lot and didn't come up with any other
option other than what I suggested in the opening of the bug report. Also, I
tend to think this is much cleaner. Like sudo itself. Like strace. Like a
billion other similar commands.

Sorry to rain on your parade. =)
