Binary package hint: gnome-session

Ubuntu Lucid 10.04 LTS, upgraded from Dapper
gnome-session: 2.30.0-0ubuntu1
libpango1.0-0: 1.28.0-0ubuntu2.1
libcairo2: 1.8.10-2ubuntu1

Every now and then I supose that the system does a maintenance checkup at (re)boot. Unfortunately I cannot see what is going on, because I only see squares. Esc does not help, ctrl-alt-backspace does not help either. There is no way I know how to skip this. The system is used for work and waiting costs precious time.

I already reinstalled all Pango packages, but it does not help.

Xorg.log says (clock is the same for all messages):

gnome-session[1340]: Pango-WARNING: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Sans 9.9990234375'

For the rest I do not have font problems on that system.
There is a font error. It seems to mention two different DejaVu Sans versions, but the version on the system is a link in /usr/share/fonts/truetype/msttcorefonts to a font in the windows directory, which is mounted in fstab. Shouldn't gnome-session or pango fall back to another font? These messages should be readable.
