Looks like you have the fglrx driver installed, which ships a libGL
which is indeed incompatible with libgl1-mesa-dri.
Good analysis ! Removing fglrx-driver (i can't remember why i installed
it on a system without an ATI graphic adapter...) solves the problem.
This probably makes this bug report become a duplicate of #401584,
concerning
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401584>fglrx-driver
("Making fglrx-driver co-exist with other 3-D drivers").
