acroread & pdfedit fail on tmp/.X11-unix/X0 socket + libXext/src/extutil.c:126 XGE not registering

[Sebastian Glita]

Hi,

Running `strace pdfedit *.pdf' this happens after filedescriptor 3 binds the X unix socket:

Tracing `strace acroread *.pdf' now would make me not send this email as X freezes, although the first page is displayed, but not interactive.
Opening the PDF in a browser with acroread plugin shows empty content.

I installed xorg-server 1.5.3, xf86-video-ati from git, everything else from git, except the new input dependency, because I have a yet unsupported input device.

I also got hangs one time ago, when in Xorg.0.log I found something like '[mi] ... entered an infinite loop ...'.
