The recent gramps application depends on GTK 3 and it needs typelib-1_0-Gtk-3_0. If typelib-1_0-Gtk-2_0 is not installed (which breaks a lot of things so not recommended), gramps will work fine on my 13.1 amd64 machine. However, having typelib-1_0-Gtk-3_0 and typelib-1_0-Gtk-2_0, the command line
gramps -e blub -O blab
produces the error
/usr/lib64/python2.7/site-packages/gi/overrides/Gtk.py:49: RuntimeWarning: You have imported the Gtk 2.0 module. Because Gtk 2.0 was not designed for use with introspection some of the interfaces and API will fail. As such this is not supported by the pygobject development team and we encourage you to port your app to Gtk 3 or greater. PyGTK is the recomended python module to use with Gtk 2.0
How can I set the preferred libs?
The strange thing is that I have an almost identical system (in the sense that I do not find a significant difference for the problem), where everything works…
Thanks a lot for input!
