Bug#880662: mate-desktop: Some Super shorcuts doesn't work

[Luffah]

Package: mate-desktop
Version: 1.18.0-1
Severity: normal

Dear Maintainer,

  i don't know if it is after updating mate packages, but i found that
some keybinds no more send event to launch programs.
  Instead of launching the program configured with
'mate-keybinding-properties', it does input the character in the focused
window.

  I use the bépo (fr-bepo) keymap.

  The keys that fails are Mod4+h Mod4+" Mod4+» (guillemetright),
  while keys  « (  work well with Mod4.

  Using Ctrl instead of Mod4 works well too.

  The program (a script to switch between nammed windows) which i binded
works with mosts of my keybindings.
  Anyway, i tested to bind : Mod4+h to glxgears (which is not a script
and works well) and the program is not lauched.

  Here a summary with the content of my configuration file and the '-->'
result of the keybind with focus on 'mate-terminal'.
! dconf dump / | grep Mod
home='<Mod4>f'                       --> OK
binding='<Mod4>Return'               --> OK
binding='<Mod4>t'                    --> OK
binding='<Mod4>p'                    --> OK
binding='<Mod4>quotedbl'             --> Fails, '"' is typed
binding='<Mod4>guillemotleft'        --> OK
binding='<Mod4>r'                    --> OK
binding='<Mod4>guillemotright'       --> Fails, '»' is typed
binding='<Mod4>h'                    --> Fails, 'h' is typed
binding='<Mod4>c'                    --> OK
binding='<Mod4>w'                    --> OK
binding='<Mod4>n'                    --> OK
cycle-group='<Mod4>space'            --> OK
switch-group='<Mod4>Tab'             --> OK
tile-to-side-e='<Mod4>eacute'        --> OK
tile-to-side-w='<Mod4>b'             --> OK
toggle-maximized='<Mod4>m'           --> OK


Have a good day.
Best regards.
