When working in the Processing modeler, if I set the parent algorithm of anything to a script, I get a QT error. Closing the error dialogue brings me back to the processing modeler, which then immediately reopens the error dialogue. Because this continues infinitely, I'm forced to kill the process and start over.
I'm convinced the error is related to the lines drawn between objects in the modeler. Whether by some bug or otherwise, sometimes when I'm working with the modeler, the lines between objects that illustrate parent relationships disappear. I've since noticed that without these lines, I can add scripts as parent algorithms without any problems at all. But the moment the lines come back, as is the case when I re-open the modeler or fiddle with the zoom, the error instantly appears.
