By default, in a Gnome session BeeRef pulls a couple of gtk/gdg libs. When opening a native Gnome/GTK file dialog, more gtk/gdl libs are loaded from the system, which might be incompatable.
Current workaround: Exclude the following libs:
"libgvfsdbus.so" "libcanberra-gtk-module.so" "libgvfscommon.so" "libcanberra-gtk3.so.0" "libgdk-3.so.0" "libgdk_pixbuf-2.0.so.0" "libgio-2.0.so.0"
