I've found the change to libmagic that brought this.
Please try temporary workaround if you have sources installed:

cd /tmp
fetch http://www.grosbein.net/file/patch-softmagic.c
cd /usr/src/contrib/file
patch -R < /tmp/patch-softmagic.c
cd /usr/src/lib/libmagic
make obj clean depend && make all install
