Comment 2 for bug 1381105

Yes I can replicate this - you have to start the camera app right after rebooting.

Attempting a workaround here: lp:~albaguirre/qtubuntu-sensors/fix-1381105 prevents the freeze but the trust-store prompt is never shown.

It looks like com::ubuntu::location::service::Stub::create_session_for_criteria times out:
