Since I didn't hear any news on this issue I did some more researching. There are two ways that I know of that a source can use to interrupt the GLib main loop: Either by specifing a timeout value, or by registering a file descriptor to poll for new input. Since my example program works with the timer code uncommented, I assume that su-glib doesn't have problems with the timeout method of interrupting the event loop. To test whether su-glib also correctly registers its UDP socket as a FD to poll, I ran my example code in gdb with breakpoints set for g_main_context_add_poll and g_source_add_poll. Neither of these breakpoints were reached before the program entered the GLib main loop. If the UDP socket is indeed not registered as a FD to poll then I think that's a pretty major bug in su-glib. Unfortunately I don't understand the sofia-sip code enough to check this throughly and tell where or when the registering of the UDP socket should take place.
