--- Comment #2 from Vincent Povirk madewokherd@gmail.com 2008-05-18 18:33:47 --- Ok, well, that's the last time I trust the menu editor to tell me anything.
In the .desktop file, the actual line is:
Exec=env WINEPREFIX="/home/meh/.wine" wine "C:\Program Files\Frasse and the Peas of Kejick\Frasse.exe" C:\windows\profiles\meh\Application Data\Frasse and the Peas of Kejick\Frasse.slg
Which I can copy/paste into a terminal, and that makes everything ok.
I can also do this:
Exec=env WINEPREFIX="/home/meh/.wine" wine "C:\Program Files\Frasse and the Peas of Kejick\Frasse.exe" "C:\windows\profiles\meh\Application" "Data\Frasse" and the Peas of "Kejick\Frasse.slg"
or this:
Exec=env WINEPREFIX="/home/meh/.wine" wine "C:\Program Files\Frasse and the Peas of Kejick\Frasse.exe" C:\\windows\\profiles\\meh\\Application Data\\Frasse and the Peas of Kejick\\Frasse.slg
Apparently .desktop requires, for a reason I do not understand, that everything weird is escaped twice.
