GNOME file manager column too small?

In Ubuntu Feisty, my new file manager folder windows have a name column that’s too small to show any text. I wonder, is this an Ubuntu Feisty-specific bug, or something that has arrived in generic GNOME 2.17/2.18. I think it’s a show-stopper for either Ubuntu or GNOME.

Update: This is fixed now, after the latest Feisty update, so it will not be a problem in the final release.
