I am not going to try to penetrate your code, and you may already know this but a GObject signal handler executes in the thread which emits on the signal. If this is a GDK/GTK+ signal, this would/should be, in almost all cases, the thread in which GTK+ runs, namely the thread of the default main context. g_idle_add() does not of itself emit a signal. It executes a callback in the main loop of the default main context.
