New Revision: 192454

URL: http://svn.asterisk.org/svn-view/asterisk?view=rev&rev=192454
Log:
Fix an incorrect assumption that certain values on the channel will always exist when they may not.

The CDR code involved with bridges wrongly assumed that the currently executing application and data
values will always exist. It is possible for this to be false when call forwarding is involved.

(closes issue #14984)
