</div>It seems that the segfault happens in the python finalization code.<br>
Such crashes happen if the qt objects are deleted in wrong order.<br>
Presumably the QApplication object has been deleted earlier than the<br>
composition. That could be solved by various ways, for example,<br>
delete the composition at the end or set QApplication to be parent of<br>
the composition.<br>
<br>
Since the code crashes in the finalization stage, you should get the<br>
output png file anyway. Can you please check?<br></blockquote><div><br></div><div>Yes, the out.png is there but it contains a blank (white) image.</div><div><br></div><div>adding </div><div><div>c.setParent(app)</div></div>
