Correct. The problem doesn't occur with libxcb1 1.1-1ubuntu1. I did notice that this is exposed by the fact that we divert /usr/bin/firefox to /usr/bin/firefox.distrib. The problem doesn't occur if /usr/bin/firefox-3.0 is called directly. I also discovered a similar error starting gnome-screensaver with the new libxcb that is not present with the original version.
