SEGV in enable_glyph_matrix_rows

[Reiner Steib]

Hi,

In GNU Emacs 21.3.50.38 (i686-pc-linux-gnu, GTK+ Version 2.2.1)
 of 2004-09-23 on lumberjack
configured using `configure '--prefix=/import/xtra/emacs/HEAD' '--with-gtk''

Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: POSIX
  value of $LC_CTYPE: en_US.ISO_8859-1
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: POSIX
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

... I got SEGV (see backtrace and xbacktrace below).  The Emacs
session is still running under gdb, so I can provide more informations
when needed.
