Today I tried an upgrade of my debian unstable machine. Didn’t do this for several months, so I expected some problems, but this one was really hard to solve. I already had openoffice 2.4 installed, so there weren’t many changes, but after the complete upgrade the free fonts disappeared (FreeSans, FreeMono, …). The font drop-down menu showed three blank lines and I was also able to type in the word “FreeSans” into the box, but all I got were blank spaces. I googled around for two hours and finally I found a hint about the ttf-freefont package: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=472830. I don’t understand exactly what’s wrong, but installing version 20060501cvs-12 from snapshot.debian.net solved the problem and the fonts get now rendered correctly.
