Bug#639925: /usr/bin/vim.gnome: WM_CLASS property differs when vim is launched as 'vim' or 'gvim';

[Sam Morris]

Package: vim-gnome
Version: 2:7.3.280-1
Severity: minor
File: /usr/bin/vim.gnome

When using gnome-shell and launching 'gvim', Vim windows get the correct
icon (high-resolution SVG icon) and display name (GVim Text Editor) in
the shell).

When launching 'vim.gnome' or 'vim', then issuing the 'gui' command, Vim
windows get the wrong icon (tiny XPM icon scaled up) and name
('vim.gnome' or 'vim', respectively), instead.

According to <https://live.gnome.org/GnomeShell/ApplicationBased>,
gnome-shell uses the WM_CLASS window property to associate application
windows with a .desktop file, and hence their display name and icon.

xprop reveals that the 'gvim' windows' WM_CLASS property is "gvim",
"Gvim", but the 'vim.gnome' and 'vim' windows' properties are
"vim.gnome", "Vim.gnome" and "vim", "Vim" respectively.

Newly created GTK+ windows obtain their class changed by a prior call to
g_set_prgname("gvim"). I guess that their current value is being based
off of the value of argv[0].

Alternatively, gtk_window_set_wmclass("gvim", "Gvim") can be called
after calling gtk_window_new.
