cannot launch kobuki_dashboard on kinetic

edit

Hi, I'm trying to setup a turtlebot on ubuntu 16, ROS kinetic.

Installation went well so far. My laptop and the turtlebot netbook can ping each other. I can roslaunch on the turtlebot fine.

I am following the tutorial at: http://wiki.ros.org/turtlebot_bringup...

When I try the command rqt -s kobuki_dashboard, I get the following error:

RosPluginProvider.load(kobuki_dashboard/KobukiDashboard) exception raised in __builtin__.__import__(kobuki_dashboard.dashboard, [KobukiDashboard]):
Traceback (most recent call last):

Same when I try to launch the dashboard via rosrun kobuki_dashboard kobuki_dashboard.

It seems to be related to QT. Any ideas how to fix?

Cheers Isaac

Edit: If I "fix" the file in question, "dashboard.py", by changing line 8 to:

from PyQt4.QtGui import QMessageBox, QAction

Then python will segfault. Here's a backtrace from gdb:
