Reported using DrKonqi
The problem is that DropJobPrivate::slotStart() schedules a new PasteJob for pasting "raw data", but in the meantime the QDrag object from Dolphin gets deleted and so does the mimeData instance that was passed to the paste job. I'm not sure if this should be fixed in Dolphin (by preventing the DropJob in the first place) or in KIO, by detecting that the mimeData is invalid (e.g. check whether the mimeData has the "application/x-dolphinplacesmodel" format) before starting the PasteJob. David, any idea?
Actually there is already a report for this crash. *** This bug has been marked as a duplicate of bug 373005 ***
