Details:

address@hidden:/tmp/findutils-rel-4-2-fixes$ find foo -printf '%F\n'
unbekannt
address@hidden:/tmp/findutils-rel-4-2-fixes$ ls -l /etc/mtab
-rw-r-----  1 root root 378 2005-11-06 11:19 /etc/mtab

This is caused by ./find/fstype.c not checking whether gnulib's
read_file_system_list returns NULL.

It might be a good idea to show a warning in this case, using something like
this:

if (NULL == entries) {
          printf("cannot read table of mounted 
filesystems:%s\n",strerror(errno));
 }

(It actually should use error() instead obviously.)
