pyqt - copying image to QClipboard crashing program

I am writing a PyQt program which I want to be able to copy to the clipboard. Currently I have the following snippet copy the code (based on this:

def copy_to_clipboard(self):
    application=QApplication(sys.argv)
    if not self.image.isNull():
        application.clipboard().setImage(self.image)

The code is copying the image, but every time it runs, the program crashes. The images aren't insanely huge (about 1000px on a side) and I have copied images much lager than this before (not with Qt).

I am getting the following exit code:

Process finished with exit code -805306369 (0xCFFFFFFF)

What is wrong?

Constructing more than one QApplication is likely the cause of the problem (you should only have 1 per process). Rather than constructing a new QApplication, just request a reference to the existing once by using QApplication.instance()
