Dear Maintainer,
An instance of GtkAdjustment may be used by another instance after the spin
button widget is destroyed.
In that case, the function "gtk_spin_button_accessible_value_changed()" will be
called with an invalid argument.
This situation is often caused when one use GtkCellRendererSpin object.
To avoid invalid call of the function, the signal handler for the "value-
changed" signal should be disconnected when the spin-button widget is
destroyed.
I found that ngraph-gtk is sometimes crashed because of this bug.
The bug is already fixed in the upstream
(https://bugzilla.gnome.org/show_bug.cgi?id=691592), however, I think the bug
should be fixed in the version libgtk-3-0 3.4.2-6.
The attached patch improve the behavior.
Tanks.

So this is fixed in 3.7.12, marking as such.
As for 3.4.2 and wheezy, it's too late to fix it there (the archive is frozen
except for critical issues).
