[Spyder 3.0.0dev, python3] TypeError: decorated slot has no signature compatible with triggered(bool)

[malfatti]

Description of your problem

When starting spyder with python bootstrap.py, splash screen appears and then spyder crashes.

What steps will reproduce the problem?

1. git clone https://github.com/spyder-ide/spyder && cd spyder
2. python3 bootstrap.py

What is the expected output? What do you see instead?
Spyder is expected to open. Instead, it crashes.

Please provide any additional information below
Maybe can be related to #3145, since I had this problem after upgrading Debian yesterday.

In python2.7, it runs fine. In python3.5:

$ python3.5 bootstrap.py

This is a general problem with Qt 5.6. I'm closing this one as a duplicate of issue #3145.
