Michi, this MR doesn't cleanly cherry pick onto RTM due to overlapping
changes from the logging work.

Could you perform the resolve for me? I'm not really sure what the
result should be in some places..

bzr branch lp:unity-scopes-api/rtm-14.09
bzr merge -c 306 lp:unity-scopes-api

Title:
  Crash in scopes run time if scope throws exception from
  PreviewQueryBase::run()

Status in the base for Ubuntu mobile products:
  In Progress
Status in unity-scopes-api package in Ubuntu:
  Fix Released
Status in unity-scopes-api package in Ubuntu RTM:
  New

Bug description:
  If a scope throws an exception from its PreviewQueryBase::run()
  implementation, the scopes run time dumps core (stack trace below).
  This affects both RTM and Vivid. I have a fix for this, which I'll MR
  tomorrow.
