This is a crash in Mesa actually (libgl1-mesa-dri). Could you catch a
debugging backtrace with 'bt full' in gdb after installing
libgl1-mesa-dri-dbg? You'll have to attach gdb to X from another machine
with ssh. Then the backtrace needs to be sent to
bugzilla.freedesktop.org product Mesa component Drivers/DRI/R200.
