All players and plugins crash when a background image is loaded, e.g.:
<smil>
<layout>
<root-layout xml:id="Player-Window" width="200" height="200">
<region xml:id="media" width="200" height="200" backgroundcolor="#C0C0ff" backgroundrepeat="repeat" backgroundimage="http://www.w3.org/2007/SMIL30/testsuite/SMIL21/Layout/bgimagesmall.jpg">
</region></root-layout></layout>
<seq>
<text region="media" src="http://www.w3.org/2007/SMIL30/testsuite/SMIL21/Layout/bkL-background-04.txt" dur="5s">
</text></seq>
</smil>
Fixed for gtk3 in rev.8922.
Crash does not happen anymore.
Background images are disabled in bgimage_loader (rev.8928).
Without the crash the background image is not drawn, because redraw_now is used and its semantics has changed for use by video renderer. Even with this fixed, the implementation is incorrect since no 2 or more regions with their own background image can be drawn properly.
