Gnome-do froze while searching for a program…

Hi,
I was just using Gnome-do to find a directory. I typed three characters and realized that the last one was not the correct one, so I type the “←” key and retyped another character.
At this time, Gnome-do froze… and make the entire window manager froze with it (in the sense that I couldn't interact with the window manager: the windows were still drawn, even a video in a browser).
I've launched aport-bug from tty1, then killed Gnome-do once the report was done. “killall gnome-do” made the window manager work again (but obviously not Gnome-do).
Martin.
