Comment 2 for bug 468898

I spent some time on the issue today, yes Adi you're right I was testing with a Jaunty DVD which has different packages than the CD version!

pmap grep ttf for firefox in Jaunty CD is:

b2285000 316 - - - r---- DejaVuSansMono.ttf
b2419000 300 - - - r---- DejaVuSerif-Bold.ttf
b24be000 560 - - - r---- DejaVuSans-Bold.ttf
b4051000 324 - - - r---- DejaVuSerif.ttf
b48eb000 608 - - - r---- DejaVuSans.ttf

and pmap grep ttf for firefox in Karmic CD is:

aebc7000 1252 - - - r---- FreeSerif.ttf
b5628000 300 - - - r---- DejaVuSerif-Bold.ttf
b5673000 560 - - - r---- DejaVuSans-Bold.ttf
b60ad000 324 - - - r---- DejaVuSerif.ttf
b723a000 608 - - - r---- DejaVuSans.ttf

So, the easy workaround for me was removing freefont folder or the ttf-freefont package... You any ideas why FF uses FreeSerif on karmic?
