Unity8 does not start with the latest ubuntu-ui-toolkit packages

ubuntu-ui-toolkit 0.1.46+13.10.20130827-0ubuntu1

With the very latest version of the UbuntuUIToolki unity8 is no longer able to start. I downgraded ubuntu-ui-toolkit to a previous version and unity8 started fine on my phone.

Here is what I see in terminal:

phablet@ubuntu-phablet:~$ unity8
__pthread_gettid -2

Registered the AalSensorPlugin types
