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.

Anyone interested in this obscure problem can get the two example files at:
