Summary:                    app_mixmonitor crash in ast_channel_spy_read_frame
Description: 
We have been experiencing a series of random crashes on our Asterisk 1.4.11

production systems when we use MixMonitor application in our dialplan.
If we coment out the line where MixMonitor is, then the problem desapear.

We are recording calls in queues with the queue mixmonitor and these not
generate prblems. 

gdb's backtrace looks exactly the same for all of the core dumps we
collected.

Versions used:

asterisk 1.4.11 (with tx and rx fax compiled) 
libpri 1.4.1 
zaptel 1.4.5.1 
spandsp 0.0.3
libtiff-3.7.1-6
fedora core 4

We are using Asterisk with about 200 SIP Grandstream phones, we also have
two queues with four SIP members, a dual span E1, and one IAX trunk with
another asterisk 1.4.6

Here is the bt output
