embed: unmap: check stage exists before unmapping (967 bytes, patch)

Description Raluca-Elena Podiuc 2011-06-26 16:51:57 UTC 
A GtkWidget's ->unmap function may be called after the ->dispose function has run.

I discovered this bug while converting Empathy's video-widget from GtkDrawingArea to GtkClutterEmbed: Empathy calls the widget's ->destroy without hiding the widget. Because of that the destroy call ran first, and after a while, the gtk would call the widget's ->unmap function.

I posted the bug here because there's no clutter-gtk entry anywhere else (at least not in gnome's and clutter's bugzillas) and that's what I was advised to do on IRC.

There is a similar check already done in gtk_clutter_embed_hide().
