After a masquerade, the surviving channel could be using the preferred codec instead of what was negotiated.
The guts of SIP/100 (clonechan) masquerades into SIP/200 (original) for call pickup.
SIP/100 (codec list: gsm, alaw) and was using alaw
After the pickup masquerade it would be using gsm.</pre>

This includes swapping the formats and capabilities.
Since the newly created channel only contains ast_format_none, this causes an assert to fire when the masqueraded channel is destroyed.
Removing the assert isn't a good idea. However, there's also no real need to do the accessing that fires the asserts either: the masqueraded channel will be destroyed, the references will be cleaned up appropriately, and life will go on. free_translation is also called in a channel destructor, and again, things will be cleaned up appropriately without going through the accessors that have the asserts.</pre>
