Hi,

I received this report from a Debian user:

| The latest emacs-snapshot aborts if I try to compile Fontifier.el
| from the mozart package.
|
| I am compiling it from dired (typing B on the line with Fontifier.el):

The file is attached to this message.

I can reproduce this bug with current CVS:
