Bug#874586: gnome-applets: Sticky keys setting has no effect anymore

[Christopher Cramer]

Package: gnome-applets
Version: 3.24.1-3+b1
Severity: normal

I have always had the "Sticky Keys" setting enabled in the accessibility
menu.  After an upgrade in the past few days, the setting stopped having
any effect.

Normally, when I press a modifier key (shift, alt, ctrl) and release it,
the next key I press should be modified. In other words, I should not
have to hold the modifier key down while I press the key to be modified.

After the problem appeared, I rebooted (because I thought maybe a new
kernel or X server or whatever was needed), but nothing changed. I've
tried toggling the setting on and off, but it still has no effect.

I have other systems where I do not use Gnome, and enable sticky keys
from the command line, so I tried that:

tsuyoshi at hiroshima:~$ xkbset sticky && xkbset exp '=sticky'
XKB not supported for display :0

So that didn't work. And maybe this problem is not fundamentally caused by
anything in gnome-applets, but by something that changed in the X server
packages. But in that case it should give me some kind of error message,
instead of silently doing nothing.
