Description:
When I open built LO components (instdir/program/scalc,  instdir/program/swriter, etc), it crashes. I'm using openSUSE 13.2 with KDE.

Terminal shows these warnings:
(soffice:27342): Gtk-WARNING **: Theme parsing error: <data>:1:59: 'min-width' is not a valid property name
(soffice:27342): Gtk-WARNING **: Theme parsing error: <data>:1:76: 'min-height' is not a valid property name
(soffice:27342): Gtk-WARNING **: Style property "min-width" is not registered

(soffice:27342): GLib-GObject-WARNING **: can't peek value table for type '<invalid>' which is not currently referenced

Backtrace also points to the GTK code:
