Ok, that seems to be the problem. /usr/X11R6/lib/libGL.so.1 pointed
to /usr/X11R6/lib/libGL.so.1.2.seg, a backup copy of libGL.so.1.2
from xlibmesa-gl I made when I tried to install the ATI proprietary
drivers a while ago. I made it point to the file of the current
xlibmesa-gl and it all works again. What puzzles me is that it was
xlibmesa-gl the one who made the link to the old file. In order to
be sure about that I deleted the link and reinstalled xlibmesa-gl.
After that the link pointed again to the old file. Is this expected
behaviour?

Thanks for your quick answer,

David
