Run the app in gdb with --g-fatal-warnings:

$ gdb myapp
(gdb) run --g-fatal-warnings
[close the window, note crash]
(gdb) backtrace

That will show where it crashes.

Of if you're wondering what the message means, it means someone tried
to gtk_timeout_remove(), gtk_idle_remove(), etc. a source ID of 0.

(gtk_timeout_remove() and friends are legacy compatibility wrappers
around g_source_remove()).
