Not true, we can avoid all the breakage inside GtkSpinButton.

That's what I proposed. If it's != 0, force it to 0 and issue a
warning. Spin controls have no concept of data set so there is no such
thing as a page and therefore there's no use for limiting the offset
to a certain subrange of (min, max). It's a two-three line change for
GTK and was already worked around in libglade (patch posted earlier in
this thread).
