While location service or posclientd using a 100% CPU might worsen the situation, I do not think that it is the gist of this bug.
In addition, the syslog pasted in #2 clearly shows that the trust and location frameworks respond promptly:

roughly indicating the start of the app. With that, I remove location-
service from the list of affected projects.

As Kevin pointed out: The entire GL pipeline stalling for a few seconds
hints towards a deeper underlying issue. The numerous ioctls logged by
the camera driver/camera service might give us a good idea of what is
going wrong.

If someone manages to reproduce reliably, please add the output of sudo
/system/bin/logcat to this bug report. Filing against

Title:
  Camera app takes 1 minute to load

Status in Camera App:
  In Progress

Bug description:
  current build number: 2
  device name: krillin
  channel: ubuntu-touch/ubuntu-rtm/14.09
  last update: 2014-09-24 20:28:13
  version version: 2
  version ubuntu: 20140924
  version device: 20140919-1b3e670
  version custom: 1411084873

  After a moment with the phone, the camera-app takes up to one minute
  to load. Immediately after a reboot it just takes a few seconds.

  When it happens the spinner is spinning for a few seconds, then
  everything hangs (UI stops responding, launcher, panel and switcher
  doesn't work) and after one minute or so the camera eventually starts
  and shell is back to normal operations.

  When it starts happening once, only a reboot makes the camera behave
  properly again.
