I added some debug code to app_queue and ran a few tests. The change in
app_queue in 1.4.9 breaks queues configured as "joinempty=yes".
If there are no members in the queue, the membercount will be 0. A queue
configured as joinempty=yes should still allow calls to be enqueued in this
case. Because go_on is zero and membercount is zero and the comparison is
"go_on >= qe.parent->membercount", any calls that attempt to join a queue
without any members will immediately get kicked back to the dialplan.

Though I can't seem to lock onto the circumstances, I also oberved this
breaking queues configured as "leavewhenempty=no". I can't seem to
replicate it using a single queue and a single member (on pause or on a call
or letting their phone ring through), but as I described in my first
message, I did see the "Exiting on time-out cycle" message last night when I
had 4 people in the queue, all on a call, and one person didn't pick up
their phone.
Still, the joinwhenempty breakage should be enough to prompt a backout or
rapid fix for this. Until recently, my dialplan didn't gracefully handle a
return from Queue() because all my queues were configured as "joinempty=yes"
and "leavewhenempty=no". Recently I added logic to kick users back to the
IVR if Queue returns for any reason, but had I not made that change,
1.4.9would have resulted in my callers getting unceremoniously hung up
on if they
tried to join a queue without agents.
I'll go open a bug report.
