I can't reproduce it in 2013, using PyQt 4.8.6. Are you sure you have the
right match of Qt/PyQt built for 2014?
Also, have you considered switching to PySide, since its bundled with 2014?
(unless you have to support backwards compatible PyQt/Maya combinations)
You could work around this problem by not using QSignalMapper at all, and
swapping to functools.partial:
from functools import partial
...
self.b1.clicked.connect(partial(self.sayIt, "B1"))
self.b2.clicked.connect(partial(self.sayIt, "B2"))
def sayIt(self, name):
print name
