[Tomas Groth]

Fix taking screenshots while using powerpoint or impress.
Fix traceback when expanding and collapsing songs.
In _process_item, postpone check for _reset_blank, since the service_item can change type while being execute (Pdf->Image). For the same reason always use the serviceitem that might have been converted.
Fix crash when sending Pdf live.
