This is _NOT_ major, and is not a 'code formatting/comments' issue at all. Please take care to categorize your bugs properly so that the proper people will pay attention to them.

The only way this can occur is if you have 'videosupport=no' (the default) in the general section of sip.conf, and you try to send a video call through Asterisk. This is a configuration error, not a bug.
