Does Slackware distribute GtkAda, or 3.18.9 is the version of GTK 
itself? GtkAda 3.14.15 is what AdaCore published with the GNAT GPL (or 
community edition they call it now). They also have a repository where 
one can get the latest changes.

Also, GTK is full of bugs that come and go. Recently I had a massive 
memory leak in one version fixed in another. Memory leakage has a direct 
connection to reference counting, so I would think it might be a GTK 
problem, first.

You could try to upgrade or downgrade and see if the bug persists. 
GtkAda usually stays compatible with a number of GTK version.
