This issue has been idle for quite a while and needs a resolution, so I am
taking over. The problem is that I am having a lot of trouble understanding
exactly what the problem is here and how to reproduce it.

Let's try to break this down into steps instead of using prose to describe
the situation. Based on the log you provided, I think this is what you have
done.

mISDN/1-1 calls SIP/905.
SIP/905 answers the call.
SIP/905 initiates a supervised transfer to mISDN/1-u0.
While mISDN/1-u0 is ringing, SIP/905 presses
http://bugs.digium.com/view.php?id=3 to disconnect the call.
...(This is where things get confusing. I may have details wrong here)...
mISDN/1-1 and SIP/905 are connected again.
It appears that SIP/905 attempts to park mISDN/1-1. It is unclear exactly
how this is being accomplished. 
mISDN/1-1 gets tired of being parked and hangs up.

In the log you uploaded, you then stopped Asterisk using the "stop now"
command. In http://bugs.digium.com/view.php?id=14007#c97069, you show that
Asterisk crashed. The initial report did
not mention a crash at all (except in the "severity" field). Did the crash
occur when you first reported this against Asterisk 1.2, or is that
something that started happening when using 1.4?

I'm going to need to know exactly the steps to follow to make this problem
happen. It is really difficult trying to figure this out just based on the
description you have provided and the files you have uploaded.

Thanks!
