hi:
I met a text update issue in CE4100 platform. When I first call
clutter_text_set_text and then show stage, it's ok. But after the stage
displayed,a segment fault will be happened in re-draw phase if I call
clutter_text_set_text to change text again.(i tried use
clutter_text_set_editable, but still the same result) below is the stack
info(use clutter1.6.2):

I also tested clutter1.4.2 version, and even tried unref the old
clutter-text and then new one to set text, but still segment fault in same
place. is it a bug? and is there any other approach to update a text in
clutter? thanks.
best wishes
