Bug#515616: release-notes: Add "Errata" fonts upgrade from etch to lenny problem

["W. Martin Borgert" <debacle@debian.org>]

I don't understand the last sentence: "The problem can be
resolved by upgrading the other parts of fontconfig
(libfontconfig1 and fontconfig-config) to the latest versions."
Do you mean users should upgrade these packages first and than
upgrade the font packages? If so, I suggest: "The problem can be 
resolved by upgrading the packages libfontconfig1 and
fontconfig-config before upgrading the rest of the system, esp.
any font packages." (Beware: I'm not a native en speaker.)
