Code review comment for lp://qastaging/~evfool/scratch/lp1309291

you know, my Isis install is really messed up these days -- I'm running gtk/glib from daily git, so it's entirely likely the code is fine, and the issue is on my end. I trust that if you've tried to reproduce this on two different computers (and it Dan hasn't run into it), it's good enough to merge.

When I get a sane install back, I'll try to reproduce, and then I'll report a bug if I can. But for now, I think it's better to just get this in trunk and keep moving forward.
