> We have observed a crash in ast_bridged_channel due to a null pointer.  We do not know at present how to reproduce it, it is something we haven't really seen before but then saw several times in a single day.
> The cause appears to be a bridged channel existing without a 'tech' field, so the ast_bridged_channel function dereferences a null pointer, the fix is quite simple and seems to work for us, we've seen no further occurences of the crash.
> *Hopefully* I still have the backtrace/core file, but if not, as I say we don't know how to reproduce it, apologies.
