setup 1-2 sip accounts

set breakpoint on transports.cxx:1965

start ekiga in debugger

... sync/timing problem, something (transport object?) 
gets deleted and then reaccessed by the timer callback handlers(?).
can be catched in resendCancel intermittend too.

i need graphical documentation of the timing/sync flow in
