Problem figured out by Trevinho and didrocks on irc: unity only emits
AcceleratorActivated() for the first id returned by GrabAccelerator()
and doesn't watch the unique name of the grabbing process. Thus, when
something other than unity-settings-daemon grabs the key before it, or
u-s-d crashes, those keys it grabbed at the very beginning can never be
regrabbed.
After a couple of rounds of testing and some code review, I can't make
unity-settings-daemon subscribe to the same accelerator twice and thus
getting into that situation itself. Feel free to reassign it to u-s-d
once unity is fixed but this problem still persists.
** Changed in: unity-settings-daemon (Ubuntu)
Status: Triaged => Invalid
