Sleeping signal is only emitted if AboutToSleep is called

Hi!
I'm one of the developer over at team-xbmc and I recently noticed that UPower have added the Sleeping and Resuming signals, awesome!
I noticed a problem with them when implementing them into xbmc however. The resuming signal works fine but the sleeping signal is only emitted if I call AboutToSleep.
According to docs its supposed to be emitted on calls to hibernate and suspend aswell, which its not. In XBMC we could easily call AboutToSleep first but gnome doesn't seem to do this and
then the event won't get emitted to us and we are kept in the dark about the sleep.
Also as an application all what I want is signals that happen when 1) a sleep will occur unless something goes terribly wrong (but note here it should be beyond the point of no return regarding cancelation of sleep). 2) on resume (this one works perfectly) and optionally 3) when the system might sleep but I have the power to cancel it.
In 1 I must assume that the system will sleep and I can do stuff like stop playback etc. and 1 second is enough to handle anything to prepare for that. 3 would be nice since then I can do certain stuff that won't interfere with the usage of the application, like auto-saving something in case the sleep would fail. This one could easily be optional for the application thats about to call since the actual suspend will still signal sleeping.
I consider the current sleep signal being 1, thus it might be abit weird to have AboutToSleep signal Sleeping since there is no obligation for another application to call suspend / hibernate. Perhaps I assume wrong here?
Thanks for an awesome job, the new UPower is otherwise extremely good! (UDisk and those are aswell very nice).
Cheers,
Tobias.
