what you are experiencing is not a bug in Emacs or in Imagemagick
As explained in http://wiki.debian.org/Xorg69To7
You will need to edit your FontPath entries in /etc/X11/xorg.conf.
/usr/lib/X11/fonts becomes /usr/share/fonts/X11/.
Alternatively, let 'dpkg-reconfigure xserver-xorg'
recreate /etc/X11/xorg.conf
Note that this does not work if you changed it by hand;
in that case, issue
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
# md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum
# dpkg-reconfigure xserver-xorg
Then restart the server. (Logout/Login of gdm or kdm is not enough!)
This latter action solved both bugs for me.
a.
