Hello togehter,
I have encountered a puzzling thing.
When I wanted to video chat with someone I discovered that the button for starting a chat conversation was missing. I now it was there in the past 
First I thought maybe its a problem of kopete, but then I cross checked it installing kmess with the same result.
So on my system in chat programs there is no button to start video chat.
Description:
in kopete in the video configuration menu the webcam is displayed, video working and configurable e.g. contrast.
But as mentioned above, no possibility to start a video chat.
kopete --version
Qt: 4.4.3
KDE: 4.2.1 (KDE 4.2.1) "release 103"
Kopete: 0.70.0

Has anyone encountered this and has an idea how to solve it?
Help is greatly appreciated.
