Package: gimp Version: 2.8.16-1 If clicking Help causes env: wine: No such file or directory then be sure to move ~/.local/share/applications/wine* out of $HOME. This tip important for former wine users on linux who have removed wine, but still have some residue in $HOME that is for some reason being picked up when Gimp tries to run its help browser.
Gimp really shouldn't be trying wine stuff over the native linux stuff first anyway too.
