Bugzilla Bug 114750

As per summary, on every system I've tried it on, the upgrade to
font-arabic-misc-0.99.1 fails in postinst.  Final output from merge is:
===================================

===========================================
So far, other fonts in 0.99.1 set do not have this problem.

Should be fixed
