GNOME Bugzilla – Bug 619680
Assigning keybindings does not work reliably in a very special case
Last modified: 2011-11-16 18:31:58 UTC
Reproduce: 1. open gnome-keybinding-properties 2. Add a command named "Blub", command "gnome-terminal", assign Ctrl+Alt+1 3. Add a command named "Blip", command "gedit", assign Ctrl+Alt+2 4. Both work as expected 5. Disable the bindings for both commands 6. Assign Ctrl+Alt+1 to Desktop/Show panel menu (backtranslated from German) (or any non-custom action) 7. the binding will not work Sorry it's such a special case, but at the moment I can't seem to reproduce the behaviour in a more general case.
Mass move to new component "Keyboard" where the keyboard shortcuts live in GNOME 3.
That was a bug in the keybindings plugin all the way up and including GNOME 3.2 which didn't know how to unbind keys. Was fixed in the development version for GNOME 3.4. *** This bug has been marked as a duplicate of bug 625228 ***
