[Gtk2hs-users] critical error reported by gtk+ in treeview demo

[<j.r...@gm...>]

Hello.

Trying some demonstration programs from gtk2hs-0.9.13 on my Gentoo Linux
~amd64 system, I am getting the following critical error at runtime:

$ ./listtest 

(listtest:27645): Gtk-WARNING **: GtkSpinButton: setting an adjustment with non-zero page size is deprecated

(listtest:27645): Gtk-WARNING **: GtkSpinButton: setting an adjustment with non-zero page size is deprecated

** (listtest:27645): CRITICAL **: gtk2hs_store_ref_node: assertion `iter->stamp == store->stamp' failed


$ pkg-config gtk+-2.0 --modversion
2.14.3



These critical errors happen when I add new rows to the tree view using
the insert, prepend and append buttons in the ListTest application. They
also happen in the new application I am starting to write (my first
gtk2hs application).

Any clues?
