Ruined my font-system?
 

Hi,
i played somewhat around with the X Font Servers xfs and xfstt to get some nice fonts working, but now this is quite broken :cry: . I can't start any GTK apps anymore as a normal user! When i log in as root, i can start them again. The app(s) say:
** (xchat:1031): WARNING **: Cannot open font file for font Bitstream Vera Sans 12

** (xchat:1031): WARNING **: Cannot open fallback font, nothing to do

strace says
[...]
open("/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType/Vera.ttf", O_RDONLY) = -1 EACCES (Permission denied)
This path symlinks to /usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf

But the permissions are correct, they are set to 644 for all the font files. When i change them to 666 it works again, but this can't be the right way to fix this (644 is always default for this files).
The fonts section of my XF86Config-4 looks like this:
FontPath "unix/:7101"
FontPath "unix/:7100"
FontPath "/usr/X11R6/lib/X11/fonts/TrueType/"
FontPath "/usr/X11R6/lib/X11/fonts/misc/"
FontPath "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled"
FontPath "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled"
FontPath "/usr/X11R6/lib/X11/fonts/Type1/"
FontPath "/usr/X11R6/lib/X11/fonts/Speedo/"
FontPath "/usr/X11R6/lib/X11/fonts/75dpi/"
FontPath "/usr/X11R6/lib/X11/fonts/100dpi/"

xfs and xfstt are running. My system is a debian one (or better said a knoppix one installed on hard disk). Anyone has an idea what's going wrong here?! :)
