Please describe the problem:
When I select "Chat -> Quit" in the menu, nothing happens.

Steps to reproduce:
1. Start Empathy
2. Set your presence to Available
3. When your contacts start to appear but before getting all your contacts, set your presence to Offline
4. Check that Gabble and Mission Control processes terminate
5. If you run GDB on Empathy, you see in the stack that it waits on empathy_run_until_ready although we are offline and Gabble/MC don't run anymore
6. Set your presence to Available
7. Menu Chat -> Quit


Actual results:
Cannot quit

Expected results:
Menu Chat->Quit should always work

Does this happen every time?
Yes

Other information:
stack at step 5.

etc.

smcv: "tp_*_run_until_ready has a hook for getting the main loop in order to be able to cancel, added specifically for the "how do I exit when things aren't ready?" use case"
