drag and drop of a file dialog

[jamat13]

I'm struggling with this, has anyone suceeded

I have a file dialog
I want to drag a file and drop on a bookmark

eg file dialog shows
video1.mp4
video2.mp4

side list shows
stuff
home
USBmemStick

I want to drag video1.mp4 to USBmemStick

What happens Drag creates a new bookmark called video1.mpg
drag and drop that on USBmemStick crashes Qt

What DOES work drag video1.mp4 to Desktopor to FileManager USBmemStick pane or use copy & paste
