Cannot change keyboard shortcuts

[ysBach]

Description of your problem

What steps will reproduce the problem?

1. Turn the spyder on and go to Preferences ->Keyboard shortcuts
2. changing any shortcut to a new one makes spyder to close with
   Segmentation fault (core dumped) spyder
   I first tried "open profiler" to "ctrl+F10" but failed. Then I tried many random changes but all failed so far.

@ccordoba12 Sorry for not attaching it from the beginning (I was not sure whether the followings are what I was asked)

$ qmake -v
QMake version 3.0
Using Qt version 5.6.2 in /home/aaa/anaconda3/bin/lib

and

from PyQt5.QtCore import QT_VERSION_STR
print(QT_VERSION_STR)
# 5.6.2
