:(  Still the same problem.  I downloaded and installed the debian 
package for 'unstable' (dated Nov. 6, 2003).  Maybe it doesn't have the 
fixes you think it should (i.e., it seemed to be for pre3 and the source 
tarball is for pre4).  I will attempt to compile pre4, but I don't think 
I will be able to get the dependencies for the compile worked out, just 
like last time.

Here are the error messages I received.  After the INFO1 <udp.c: 292> 
Sending message line, the '(null)' you see is right after modifying the 
configuration preferences screen for SIP where you put in the SIP 
registrar address and click 'Apply'.  Some part of linphone then crashes 
and GNOME throws up an error with a Segmentation Fault, but the GUI 
still runs, although it doesn't seem to work properly after that.
