Unhandled exception when another application is using the microphone

[eoinnorris]

There is an unhandled exception when a user uses the voice recognition while a call is going on, or in fact where there are any other users of the microphone. Im not sure what the exception is exactly as the exception isn't specifically explained in the external reports I get. Ill try and fix this myself if I can.

To reproduce:

1 ) build an app with Voice 2) Start a phone call. 3) Use the Voice start call 4) Theres an exception below the Objective C level but it could be handled at the Objective C level.
