Re: [GnomeMeeting-list] Gnomemeeting crashes suddenly

What version of GnomeMeeting?
0.93.0?
0.85.1
Can you provide a stack trace in gdb? It is probably a bug in pwlib or
GnomeMeeting triggered by a malfunction of your video driver. What is
your video driver? It can also be a conflict between installed OpenH323
and PWlib libraries. It happens when you are using conflicting libraries
that were not compiled together, or when you install things using
--force.

This is the debug tracer that I received at the moment I received the segmentation fault error. The version of Gnomemeeting I am running is 0.85.1, it is the latest binary stable version of Linux-mandrake 8.2.

My cam is a AIPTEK Dual-Mod plugged in a USB port. I Guess that my main problem is the fact that the version I am running, is too old, despite it is the last one in Linux-Mandrake 8.2 stable repository.

What version of GnomeMeeting?
0.93.0?

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

If you don't have a gatekeeper, then you should not choose to register
to it. You should select "Do not register to a gatekeeper", which is the
default option.

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/,

to go to visit the Homepage of "Gnome  Application Crash" for more

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

Without stack trace it is very difficult. Nobody never reported any
crash due to video problems since the begin GnomeMeeting. If you provide
the video driver and the version of GnomeMeeting you are using, perhaps
we can help. Also, the last release of GnomeMeeting 0.93, you should at
least upgrade to this version and see if the problem still occurs. Huge
improvements have been made in GnomeMeeting 0.93 (which requires Gnome2
libraries).
