baloo_file_extractor: call QProcess::close before destroying the QProcess
Review Request #125306 - Created Sept. 19, 2015 and submitted
Also there is no need to allocate memory for the QProcess on the heap. Calling close kills the baloo_file_extractor before we destroy the object therefore preventing the warnings of the type QProcess destroyed while baloo_file_extractor is still running.
baloo works as before
