Bug 157418

Version:           0.12.7 (using KDE 3.5.8)
Installed from:    Ubuntu Packages
OS:                Linux

The problem is as follows:
My friends use MSN Messenger Live Plus in their computer while talking to me on my Kopete 0.12.7 under KDE 3.5.8.
We try to send each other webcam images.
If the one sending is me, it will simply ignore the request (I send, he accepts and nothing happens). This seems to be discussed in other bugs, so I won't go on with this.
However, if the one sending is he, I will get the acceptance message, then wait for something to happen, and the recieve a crash message. saying kpete produced signal 11 (SIGSEGV), which usually means that the aplication has a failure. Here follows the inverse trace (I hope i'm getting the translations ok since my system is in spanish and says 'Trazado inverso'). Once this message appears, kopete will just close itself and I have to open it up again.
I remember once being able to see someone on the webcam, some 5 months ago. I can also see myself if I enter the "configure..." screen for video devices so my cam works ok.
I'd be delighted to recieve a solution to either of the two problems. Thanks a lot!

PS: I read that the solution to the first mentioned is to open ports 6891:6901 for *UDP*, but I don't really know what it means. Could someone tell me please?
