In Debian with the msttcorefonts package, you get the Webdings and Wingdings TTF fonts. Those render captchas that the user can't decipher (eg: they'd have to figure out what letter the "fire truck" symbol corresponds to). This very simple patch excludes webdings and wingdings from the font list.

This involves hardcoding of values; i have many ITC clipart fonts that will also show up in this case - we can't go on adding stuff infinitely!

It's best to have a few carefully selected fonts set up for Captcha. Too many fonts == too much for the user.
