which means a crash inside libGL, from a call that should be (and is on
x86-32) completely harmless. :-/

oh, cool. the code has changed a lot, so backporting isn't an option,
though.

Neil already has ported fluttr to clutter trunk - it hasn't been
committed yet because we are investigating troubles emerged with the
timeline pool and libneon (which is used to get stuff via http). the
timeline pool issue might be solvable using an environment switch - we
are still testing.

if you want to try clutter trunk you can use opt (is under clutter/toys
as well), which has been ported and it's known to work on x86-32.

sure it does! testing is always well accepted.

the "input-event" was renamed "event" in clutter trunk.

if nothing appears, you can try with:

  export CLUTTER_TIMELINE=no-pool

before launching fluttr. this disables the timeline pool, which might
cause issues with heavily threaded libraries that do not play nicely
with the GLib main loop.
