REVISION SUMMARY
  When the state defaults to AC-powered, the indexer may start some
  energy consuming tasks, only to stop these later when the pending
  DBus call finishes. Especially the content indexer can take a while
  to stop, until the current batch is finished.
  
  In case the DBus call fails AC-powered is assumed, to match the previous
  default.

TEST PLAN
  unplug AC power
  start baloo_file
  -> the content indexer no longer processes its first batch

REPOSITORY
  R293 Baloo

BRANCH
  scheduler
