The problem is that I have not yet tested debugging crashes/freezes on 
Windows...  There is some info at 
http://wiki.ekiga.org/index.php/Debugging_Ekiga#How_to_get_a_stack_backtrace_from_a_crash, 
but I think it is obsolete.  There is someone who work on this.  In the 
meantime, please post a bug report with this issue, so that we do not 
forget it.

Thanks,
