Comment 26 for bug 278078

I might have the same bug, but for me all key share the problem.

1. Go to System->Preferences->Keyboard.
2. Go to Layouts tab.
3. "Key presses repeat when key is held down" chekbox is checked.
4. Place cursor in the field, hold the key. only one letter appear even if i hold one minute.
4. Move the Delay rule a litlle.
5. Now, it will works normally for ten minutes ...

It appears after i got some issue with my keyboard (it simply stop working in gnome) and be forced to install 'xserver-xorg-input-all'
