Subject: startPreviewJob: if items is empty, delay call to slotPreviewJobFinshed
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/e7a9d5590b8e4c0b11df6b4ef7c16db046208bca

startPreviewJob: if items is empty, delay call to slotPreviewJobFinshed

This should prevent that other functions, which start preview jobs,
eventually call themselves and thus cause trouble.
