# cat /usr/share/applications/wine-winecfg.desktop|grep Categories
Categories=Wine;

# desktop-file-validate /usr/share/applications/wine-winecfg.desktop
/usr/share/applications/wine-winecfg.desktop: error: value "Wine;" for
key "Categories" in group "Desktop Entry" contains an unregistered
value "Wine"; values extending the format should start with
"X-" 
/usr/share/applications/wine-winecfg.desktop: hint: value "Wine;"
for key "Categories" in group "Desktop Entry" does not contain a
registered main category; application might only show up in a
"catch-all" section of the application menu

For your Exec key issue, at
http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s06.html
it is no mention of environmental variables, but it is that:
"The Exec key must contain a command line. A command line consists of
an executable program optionally followed by one or more arguments."

This imply the command line must begin by the executable, not by a
variable. So, this is a bug in wine which generate a buggy desktop file.
BTW, I don't know how you get it, because in my install I have:

# cat /usr/share/applications/wine.desktop|grep Exec
Exec=wine start /unix %f

and I checked the gentoo ebuild, it doesn't modify the desktop files,
but have an internal workaround for the non standard category to not
generate a warning during the installation. (Normally, each desktop file
are checked by portage for conformity, and portage complain when it is
not the case. This check is skipped by the ebuild as wine provide
extra files in /etc/xdg/menus and /usr/share/desktop-directories to
deal with that non standard category.)
