[clutter] Why create a texture in a thread failed?

[Jianchun Zhou]

Dear list:

In Clutter, Can I create a worker thread for creating actors and add them
into the stage?

I found when creating ClutterRectangle, It can work, but when it comes to
ClutterTexture, it failed.

Can anybody help me.

Thanks.
