libjingle-0.5.2 hangs after rejecting incomming call

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build libjingle with local\global multi-threaded sigslot strategy enabled
2. Make video\voice call
3. Reject the session

What is the expected output?
- Session should be properly rejected

What do you see instead?
- libjingle hangs

What version of the product are you using? On what operating system?
- libjingle-0.5.2
- Linux Ubuntu

Remark:
I debugged this issue and found that this could be reproduced only under Linux 
OS when using local multithreaded strategy in sigslot. The non-recursive mutex 
is used. In case the same signal is called from it's slot on the same thread 
deadlock occurs - mutex is already locked.
To overcome this problem I added initialization of mutex in sigslot 
local\global multithreaded strategy to be recursive.

I'm not able to repro this using libjingle 0.5.6. The call client doesn't hang. 
Try to press "Enter" to see the option menu.
