Bug Description

I got the similar error on touch device as well today morning before I reflashed it.

sudo apt-get install unity-autopilot
autopilot run unity.tests.test_panel.PanelCrossMonitorsTests.test_hovering_indicators_on_multiple_monitors

On touch I used:
[unknown what I had done before on the device]
adb shell
apt-get install unity8-autopilot
exit
phablet-test-run -n unity8

There the error message was the same except for module+directories referring to unity8.

I've verified that at least Python 2.7 2.7.5-8ubuntu4 works as intended, and 2.7.6-2 is broken.

Confirming that same problem with 2.7.6-1ubuntu1 and 2.7.6-1, but fixed if I downgrade to 2.7.5-8ubuntu4.

Looks like fallout from http://bugs.python.org/issue19352 which landed in https://launchpad.net/ubuntu/+source/python2.7/2.7.6-2.

Simple reproducer on a current trusty desktop with python-lazr.uri installed:

$ python -m unittest discover lazr

Note that this is causing pretty much all autopilot tests to fail now, so severity critical.
