+As reported by Mikko Rapeli and Tom Vogt at
+http://bugzilla.mozilla.org/show_bug.cgi?id=115788 and
+http://bugzilla.mozilla.org/show_bug.cgi?id=150339 the X server can
+abort when Mozilla requests a huge (scalable) font. This is also
+likely to happen to the X font server, or to Xvnc.
+
+This patch is from
