colord crashed with SIGSEGV in cd_profile_register_object()

[Francis Ginther]

Crash occurred after the following sequence:
 1. Login as default user
 2. Switch to guest account via the session-indictor
 3. Open gedit from the Dash
 4. Close gedit
 5. Open and close the Dash again
 6. Logout of the guest session via the system-indicator
 7. Log back in the default user account
 8. Observe crash

This was discovered while running a unity manual-test from Dash.txt (the test passed other then the crash in colord):

Dash no-results-hint
--------------------
This tests that the text displaying "Sorry nothing matches your search" is hidden when results are present (even in hard-to-automatically-test scenarios).

Action:
#. Start guest session
#. Open the Dash - there shouldn't be any results displayed, since this user
   account didn't interact with anything yet
#. Run an application not present in the launcher (for example gedit)
#. Close previously opened application

Outcome:
  When Dash is opened 'gedit' (or application you launched) should be
  displayed in the "Recent Apps" category. You shouldn't see
  "Sorry nothing matches your search" text.
