+Subject: [PATCH] Don't leak MimeData object
+
+Summary:
+A DeclarativeDropArea creates a new DeclarativeDragDropEvent on every
+enter/move/leave event.
+
+The getter method for the mimeData property creates a new MimeData
+QObject wrapper, which then leaks.
+
+Use of the mimeData object outside of the event shouldn't be expected to
+work, and a quick grep couldn't find any usage.
