I was able to track this problem down to the statements:
in the pyuic generated PreferencesForm.languageChange().
Commenting out those lines makes the crash vanish.
Funny is, I cannot reproduce this effect in a minimal example:
from qt import *
app = QApplication(sys.argv)
button = QPushButton("&Hello World", None)
