Comment 5 for bug 1211831

I added a workaround for this in banshee (well, actually, hyena, the widget-library used by Banshee), just in case some people want to run BansheeGTK3 in Ubuntu 13.04 (before this bug is fixed):

https://git.gnome.org/browse/hyena/commit/?h=gtk3&id=2ad445774ebd6a20f46e113ce11e1847fd77ca19

This screenshot is the result: it fixes 2 of the 3 cases (unfortunately, the 3rd case uses a treeview, not a custom widget, so I'm unable to fix it from the banshee code).
