the stack trace is sadly not very useful.

can you provide a small, self-contained test case exhibiting the same issue?

looking at the various backtraces, I found that this is a duplicate of this bug:

http://bugzilla.clutter-project.org/show_bug.cgi?id=2621

which was fixed in master, but not backported.

I just pushed the following commit:


commit f3532c3335d963402c5dc38d388c41e2491b0be4
Author: Chris Lord <chris@linux.intel.com>

    actor: Ensure the validity of the queue_redraw_entry pointer
    
    In _clutter_actor_queue_redraw_with_clip, there was the possibility that
    the actor will add itself to the stage's redraw queue without keeping track
    of the allocated list member.
    
    In clutter_actor_unparent, the redraw queue entry was being invalidated
    before the mapped notify signal was being fired, meaning that queueing a
    redraw of an unmapped actor in the mapped notification callback could
    cause a crash.

    (cherry picked from commit f9d7650b97c3788763e14ce3b39f21f19edc41bb)
    
    Signed-off-by: Emmanuele Bassi <ebassi@linux.intel.com>

to the clutter-1.6 branch, and that should hopefully fix the issue.
