I'm running up-to-date Debian Lenny for x86-64. I am using the iceweasel browser.
I browse to the web page crypto.org/blog and see the following:
It looks like a ransom note! tHe texT iS VarYinG iN SiZe (except that the letters are all lower case, differing in size by about a point and a half).
It renders fine on all other browsers. (See for yourself.)
Please don't suggest installing the Microsoft fonts. I am looking to fix the problem rendering the existing fonts (that doesn't occur on other Debian-derived distros), not add new ones.
