REVISION SUMMARY
  The 'name' argument is in most cases empty by which the caller indicates that
  they want the default backend. As such repeated calls to loadBackendInProcess(QString())
  cause to instantiate a new backend every time, because the name check in the
  condition is never true.

REPOSITORY
  R110 KScreen Library

  master
