[gtk-vnc-devel] rare blowup and crash when trying to delete widget...

[Rob Stoddard <rstoddard telanetix com>]

I have witnessed a rather rare crash a few times,  enough times to know 
what it is and why it's happening.  When the widget is destroyed by the 
application, but the connection is still "good" it may try to refresh 
the screen while the widget is being destroyed.  It doesn't happen very 
often, but if one were to simply check for errors at the top of 
gvnc_server_message() and return 0 if there have been errors, this 
problem would evaporate....

if(ret < 0) {
   GVNCDEBUG("Aborting message processing on error.\n);
   return !gvnc_has_error(gvnc);
}

if(gvnc_has_error(gvnc)) return 0;    /* Add this line */

switch(msg) {

... and so on.

I'd send a diff,  but my at-work dev machine doesn't have your current 
sources nor mercurial.
