I suppose it is extremely difficult to run Ekiga in gdb, hit ctrl-C when
it deadlocks and type 'threads apply all bt' ? The difficult part being
the Ctrl-C. Every time I tried, it was exiting gdb instead of
interrupting the program execution or do you have a tip for that ?
Robert will certainly ask for a backtrace.
Does the -d4 tell something interesting? (compared to a working version,
ie XP).
