libXenoStep.so

Any gtk app I start from a console moans: Gtk-WARNING **: Unable to locate loadable module in module_path: "libXenoStep.so" everything seems to work fine though, no propblems. I checked, and sure enough, the file isn't on my hard drive, and searching for it in Yast2-software-install didn't show anything either. So just out of curiosity, what is libXenoStep.so and what package should it be part of? Thanks Hans
