Subject: [Ekiga-list] ekiga crash on answering call
Date: Tue, 27 Jan 2009 13:55:06 +0530
Hi,
I have been working on ekiga 3.0.2 for quite some time now and have not been able to find out a solution to my problem. I am using a system with linux and another with windows XP for my work and trying to make a video call using sip as well as h323 protocols with H264 video encode/decode. As soon as I accept the call on windows machine, ekiga running on linux crashes and I see a segmentation fault being reported in the terminal. I am attaching the gdb-ekiga.txt file output for your reference.
Thanks,
Chaitanya
