Minimal reproducing example:

class PesterText:
    def __init__(self):
        self.urls = {}

class PesterConvo:
    def __init__(self):
        self.textArea = PesterText()

    def closeEvent(self, event):
        for movie in self.textArea.urls.copy():
            del movie

Here's an even minimal-er reproducer:

for var in {}.copy():
    del var
