Will you try Asterisk 1.6.1?

I'm afraid that the changes necessary to address this crash are extremely
invasive, and may be too much to do in 1.6.0.  Specifically, I am talking
about the reference counted object handling of the sip_pvt data structure.

However, 1.6.1 has these improvements.  So, if you use 1.6.1, they should
go away.

If you get a chance to try 1.6.1, please report back.

Thanks.
