[Epiphany] Wierd mozilla based crash (fonts)

[mike <mike redtux demon co uk>]

For info I have come across a very strange crasher bug in mozilla and
epiphany

On some sites (example www.friendsreunited.co.uk)
both mozilla and epiphany will crash on standard font settings silently.

On mozilla if you change the font to a named one, (not sans/serif) it
works

On epiphany, if you force your fonts to be used it works (ie: check
"always use these fonts")

the printer lookup page on linuxprintin.org is also affected.
