I'm guessing you mean abort?
This is likely caused by a python exception - if you start your
application in a terminal with python.exe it should tell you more.

How are you interrogating it?

So it *does* have a setText method then, otherwise that wouldn't work.

This works as you'd expect:
from PyQt5.QtWidgets import QLabel, QApplication
app = QApplication([])
label = QLabel()
text = "I am a string"
label.setText(text)
label.show()
app.exec_()
My guess would be that the thing you're passing to setText is not
actually a string, but something else.
