It all started in mansheiet naser when we were installing the lab.
The LAN server was installed by alaa, Alaa did an update, and installed windows fonts.
Then we did a reboot because we installed an updated kernel.
And here comes the bad part...
X starts then exits, Nothing wrong in the logs, Yet kdm doesn't start, Oh come on!
Maybe it's the DRI ? disable dri ? switch the driver to vesa ? No way, The piece of iron won't let X start.
X starts fine, So it's not an X problem.
Maybe a memory corruption ? memtest86 didn't find anything.
I was away trying configuring mplayer to work fine with arts, When I came back Alaa noticed that only Gtk and Qt apps are affected, He thought it might be a font problem, Running fc-cache -f -v as I suggested caused a segfault when trying to parse the windows fonts directory.
Nice, Now how to know the font causing the problem ? Ezabi noted the core file, I said run gdb, Alaa said run strings and it was it, the New_21.ttf file.
The segfault ir reproducable on both Mandrake 10.1 Official and Debian sarge.
running fc-cache under gdb, I obtained the following backtrace:
Program received signal SIGSEGV, Segmentation fault.

I'm not that experienced with fontconfig otherwise i'd have tried to fix it.
Anyway, This is a proof that I have all the rights to hate Xft/fontconfig ;-)
