[Gtk-sharp-list] Custom CellRendererText problem help!

[Christian Hoff]

You can try to use the experimental Medsphere installer, see 
http://lists.ximian.com/pipermail/gtk-sharp-list/2008-October/009078.html.

If it still doesn't work you can file a bug report with a small example 
and I'll look into it.
