Bug 424161: Unable to change the wallpaper via drag and drop
https://bugs.kde.org/show_bug.cgi?id=3D424161



--- Description ---
When I drag an image from Dolphin and drop it into the desktop area and then
click on the "Set Image" option , the wallpaper doesn't change at all.I get=
 the
following messages from the output of the "plasmashell" command in terminal
after doing that:
```
Arrived mimeData (QUrl("file:///dragged_image_URI/Cloud%231.jpg"))
("text/uri-list", "text/plain", "application/x-kde4-urilist") at 912 ,	12
Mimetype Job returns. "image/jpeg"
Received a suitable dropEvent at  QPoint(912,12)
Bailing out. Cannot find associated dropEvent related to the TransferJob
Creating menu for:  "image/jpeg"
QMetaObject::invokeMethod: No such method
StackView_QMLTYPE_127_QML_128::setUrl(QVariant)
```

After that the desired image gets to the list of the recent wallpapers in t=
he
"Desktop Settings --- Plasma" window (right-click on the desktop->Configure
desktop) , but I'm also unable to set the wallpaper by the means of that.


STEPS TO REPRODUCE
1. Drag an image into the desktop area from the file-manager
2. Click on the "Set Image" option from the appeared drop-down menu
