Nautilus and/or ext4 killed three folders!

[Borden Rhodes <jrvp@bordenrhodes.com>]

I'm not quite sure how to debug or report this one which is why I'm
mentioning it here.  I was moving to a new hard drive and copying
/home/ files from my old hard drive to my new one.  I opened Nautilus
and was dragging and dropping folders to my new hard drive when I
selected three such folders and mid-dragging, they disappeared!  After
a few searches, there is definitely no trace of them whatsoever either
on my old drive or my new drive.  I downloaded and ran extundelete on
my old drive which didn't find anything even with the --recover-all
switch.  It seems that the dragging process destroyed all trace of the
files.

Luckily, I had those folders on a backup and firearms are regulated in
Canada.  However, I'm assuming that destroying folders isn't part of
the design of Linux so I'd like to file a bug but I don't know what
evidence to collect.  Can someone help?

With thanks,

Borden
