Invisible fonts (gtk2,dejavu-fonts)

[Viczinger Dániel <pdw chello hu>]

Hi!

I've the following problem with all gtk2 apps 
(firefox,openoffice,adobereader) I've tried:

Looks nice does it? :)

I am running Slackware-current, (with 2.6.24.3) which has the following 
(relevant) packages:

gtk+2-2.12.8
fontconfig-2.4.2
pango-1.19.4
cairo-1.4.14
firefox-2.0.0.12
dejavu-fonts-ttf-2.24
xorg-server-1.4.0.90

I think the problems is quite self-explanatory so I'll only list what I've 
tried so far:

- fc-cache -r (and -f, which also runs during every bootup in slackware)
- reinstalling all these packages
- In fact, I've also reinstalled the whole OS.
- downgrading all these packages including xorg to 1.3
- dejavu added 4 scripts to /etc/fonts/conf.d/ which I've tried removing, 
to no avail.

What's even more weird that this issue only occurs on my laptop, my 
desktop running the same OS and 99% (that 1% is made of cups, 
wpa_supplicant and such seemingly non-relevant programs) is working 
perfectly fine.

I know this must be a local issue as neither google nor anyone on regular 
slackware channels encountered this, but I'm quite desperate...

Can anyone point in some debugging directions?
Thanks in advance...
