crash can be easily reproduced as follows:

I'm testing now SVN-branch-1.4-r85057. A couple of things to tell you:

Found a way to make * crash. I made several attended transfers to queues
which didn't crash, then tried this: made a call to a queue A, picked the
call with an eyebeam A, then atx to another queue B, picked this second
call with another eyebeam, then atx to another queue C, then crash. Just
after the crash tried this again and asterisk didn't crash. 
This scenario may look quite complicated, but in our production machine is
perfectly possible and understandable.


I also tried the latest patch for bug 10406, and asterisk will crash after
every attended transfer to queues with the eyebeam. Tested it with linksys
phones, and it doesn't crash.

I noticed too that the number of channels used for the transfer changes
from one model and version to another. 

I'm uploading my current configuration and the core show channels for
different tests
