Porting GnomeMeeting

Hi all,

I started to port GnomeMeeting to Gnome2 and GTK2 a few days ago, and it
has proven to be a complete disaster.
The last version of GnomeMeeting was very stable (we have made tests and
stopped GM after 700 calls), now GnomeMeeting, with the same code,
crashes every 2 calls.

It seems to always happen because of threads. I always get XLib
Asynchronous Reply, even after the GDK lock is taken (Im sure it is
taken, and moreover it has always worked since more than one year).

Other common problem is a crash of this type while drawing the webcam
image in the drawing_area... :

Im completely puzzled. What has changed so much with threads except the
fact that I need to call gdk_threads_init ()?  The code is *exactly* the
same (Im even using broken and deprecated things).

Thanks for your help.
