Comment 41 for bug 1620300

I run Kubuntu 16.10 with Spyder 3.0.2, and got back Spyder running after this fix here.

But one of my scripts crashes which was running under Kubuntu 16.04, I think it is due to the missing dependencies mentioned above (e.g. #35) when calling a matplotlib-function:

When doing "fig, ax = plt.subplots(figsize=(8, 6))"
I get:

QObject::connect: Cannot connect NavigationToolbar2QT::message(QString) to (null)::_show_message()

Could you confirm this is indeed related to the missing dependencies, and if yes, any idea how to fix it?
