Hi!

  Sometimes "randomly" my X session crashes. The only trace I was so
  far able to see is

slim[1734]: X: ../../glamor/glamor_vbo.c:70: glamor_get_vbo_space: Assertion `epoxy_glGetError() == 0' failed.

You can find out what triggers the GL error state by installing the
xserver-xorg-core-dbg package and attaching gdb to the Xorg process
(preferably from another machine via ssh) and setting a breakpoint in
_mesa_error. When the breakpoint triggers, get a backtrace with 'bt
full'. Keep doing this until the assertion fails, then let's take a look
at the backtrace of the last time _mesa_error was called before that.
