+Subject: [PATCH] Fix crash in DropJob
+
+QMimeData is owned by the backend and can be deleted during any event
+processing.
+
+DropJob has a deferred start operation. One path in this is to call
+PasteJob with mimedata. It could be dangling by this point.
+
+Pastejob follows a similar pattern in
+1d668a9fe65c5bc178487fc32e6662ff815147f6 internally but we also need to
+handle this usage before PasteJob.
