[PyQt] QLabel is visible but isVisible() is always false

First the objects are created with visible = false:

self.labelModuleArcs = QLabel("\nArc types in the module:") self.labelModuleArcs.setVisible(FALSE)

And after a while the dialog is updated (in another method but in the same class) and the label is shown but the print says false:

if object.isInModule:
   print "isVisible:", self.labelModuleArcs.isVisible()

I have 4.2.2 installed under windows and it does not work for me. I always get false.

Can you post some minimal example code that demonstrates this? It works
for me with Qt 4.2.2, so either something changed after 4.2.1 or you've
done something different to me.
