While running drracket on Fedora Core 9, I got a bunch of stderr messages from Gdk:

I'm assuming these are unimportant, and in all likelihood related to the old libgdk that's a part of fedora core 9; if they're not, let me know and I'll try to reproduce them. Since the machines that my students will be using are all Fedora Core 11, I'm betting that I won't see this error again. John
