Summary:                    Segmentation fault with incoming calls
Description: 
For this issue, my chan_mobile version is 1.6.2, and my asterisk version is
1.6.2(beta2)

Having had problems with dtmf being accepted for incoming calls using
chan_mobile v. 1.6.1 and asterisk v. 1.6.1, I upgraded both to version
1.6.2.  However, now 90% of the time any incoming call is received,
asterisk immediately shuts down, and a segmentation fault occurs (however,
in the 10% of the time that it works, everything works perfectly during the
duration of the call, including dtmf)

My extensions.conf file is as follows:

[my-phone]
exten => s,1,Answer()
exten => s,n,Wait(1)
exten => s,n,Authenticate(1234)
exten => s,n,Background(vm-enter-num-to-call)
exten => s,n,Wait(1)
exten => s,n,Hangup()


Using gdb, here is the backtrace of the core that is saved after the
segfault:
