asterisk users - Aug 2006 - Agent Transfer Locking up Queue() Application

We encountered a problem recently where, if an agent who received a call from a
queue, tried to transfer the caller with the Polycom transfer keys, it would
cause the Queue application to completely lock up.

This bug seems to be similar.

and this seems to be relevant as well:

For the moment, we have agents transferring queue callers with #1, #2, which is
hard to use. Sometimes Asterisk doesn't detect #1 correctly.

Anyone know if this problem has been fixed in 1.4, or the latest bleeding edge
code?
