avoid divide-by-zero condition for certain font files and warn about it

Me neither, but in Debian we have attached patch since 1.7.46. It's quite
similar to your test patch, just placed 6 lines later in the code (your patch
applies to line 5710 today).

Or did you have something completely different in mind?

Is there any reason not to apply one of these patches which prevents division
by zero?
