asterisk users - Nov 2012 - Channelvariables not set in Newchannel event and DADHIChannel

I'd like to receive channelvariables in my AMI-events. Unfortunately this
seems not to work for Newchannel- and DAHDIChannel- events caused by an
Originate.
In manager.conf I putted the following line:
channelvars=CHANNEL(uniqueid),AJ_TRACE_ID . Only CHANNEL(uniqueid) appears to
work for every event.

This seems like a bug to me, or is there a purpose for this behaviour?
Anyway, receiving channelvariables in Newchannel- and DAHDIChannel- events would
be a very useful functionality for my application.

Best regards,
Arjan Kroon

Below you'll find some information about my testcase.


Asterisk 1.8.15

settings in manager.conf

[general]
channelvars=CHANNEL(uniqueid),AJ_TRACE_ID

flow

2) Newchannel event received without AJ_TRACE_ID set
3) DAHDIChannel event received without AJ_TRACE_ID set
4) NewAccountCode event received and AJ_TRACE_ID is set
