Patch proposal

I forgot to mention this before, but after checking it with gdb and 'threads apply all bt' it does not look to me as a threading issue, but more related to the fact that we are calling dragSourceEndedAt() with DragOperationNone as the 'operation' parameter, so I wonder if that's what's causing that we dataTransfer is null in this case (thus the need for the check)

I'm also currently attaching the patch that I've been testing today, to make it easier to discuss.
