On my system emacs crashes at startup if the function
ftfont_cache_data in ftfont.c accesses the variable
fontset->fonts. This variable is on my system NULL. The following
workaround fixes the problem.

Do you still see this problem with latest (unpatched) CVS?  I can't
reproduce it on my computer (x86_64-unknown-linux-gnu, GTK+ Version
2.12.9).

With the latest CVS code this is fixed!
