[GnomeMeeting-list] Gnomemeeting crashes suddenly

[Antonio Carlos Ribeiro Nogueira <nogueira emc ufsc br>]

I don't know what is happening, but I am trying to run Gnomemeeting 
under Linux-Mandrake 8.2 in a Pentium III 850 MHz, with at
least 4Gb of HD allowable space, connected a LAN fairly fast. Well, 
first I as soon Gnomemeeting pops up, I receive the following message:
"No gatekeeper found". I don't know how to configure "H.323 Gatekeeper  
Settings". What must input in the "Gatekeeper host" and in the 
"Gatekeeper ID" box? Please, if it exisits especific numbers (IP's) or 
Machine Names, please give me some numbers of examples I can use. May I 
leave them blank?
After that I found a ILS Directory "netmeeting.cable.net.co" I met a lot 
of people logged on. But when I call some of them, I receive the 
following error message: "Error while opening video device /dev/video0/, 
channel 1 A teste image will be transmitted. When the my image starts to 
be transmitted, Gnomemeeting crashes. The smae happens when I try to see 
my self image. I can get the image for a very short time and then 
Gnomemeeting crashes reporting me an "Segmentation Fault" and telling me 
to go to visit the Homepage of "Gnome  Application Crash" for more 
information. I am not being able to send messages. I digit and send the 
messages, but they don't arrives to the other people. But I am receiving 
the images of the remote machines I am connected. When I use xawtv the 
cam is working fine also. I can see my self image also without crashing.
Hope you may help me
