Short description of error
When clicking and dragging files around like crazy, a double-free may occur.
Exact steps for others to reproduce the error
Clicking with all mouse buttons, dragging around like crazy may reproduce.
Attached is a Video, but I wasn't able to isolate some specific steps.
This bug is very hard to reproduce reliably.
Notice in the video:
@00:08 - I'm dragging a folder, but have no mouse button down
@00:35 - Here the bug "starts". Blender becomes unresponsive and eventually crashes.
I've attached the crash log for the crash in the video.
I've also three additional crash logs, each has a slightly different stacktrace.
