Comment 19 for bug 334544

This change doesn't fix all other keyboard navigation issues for libindicator based applets reported in bug #519195. That bug was marked as a duplicate of this, bug keyboard is still a mess (while that bug summary couuld needs to be updated).

To test, unplug your mouse[1], press Super+S and try to switch back to focus, for instance, your desktop.

[1] this is a basic test rule for any GNOME application or component, software unusable with keyboard only is a poor quality software for GNOME standards.
