Attached are two small programs, gtk.c and x11.c. Both are meant to demonstrate how to use a GdkAtom/Atom to determine if an instance of a program is already running (Linux/Unix).
I've finally tracked down the problem. When the call to gdk_selection_owner_get() is done, the proper selection XID is returned as being the owner of the selection, but there is no entry in the GtkDisplay's XID hashtable (xid_ht).
The value of the XIDs look suspiciously like temporary values, so the selection might have to be owned later, when a real XID exists. More experiments later.
This is true for versions gtk+ 2.2.4, 2.7.2 and 2.8.9.
