However, once I imported QtMultimedia, my bundled app began crashing on start up. I got the following in the Console:

However, I don’t use the QtNetwork module (and I get a warning about importing an unused module from Eric). This might mean something is up with QtMultimedia or PyQt5?

QtMultimedia has an internal dependency on QtNetwork. Presumably py2app doesn't know about this.
