OS : Lubuntu 12.04 Precise Pangolin
PCManFM Version : 0.9.10
=== Setup ===
1. Two different NTFS partitions/drives must be mounted. Lets call them /media/NTFS1 and /media/NTFS2
2. Issue the following commands (or do the equivalent via GUI in pcmanfm)
$ cd /media/NTFS1
$ mkdir abc # source directory
$ cd abc
$ touch 1 2 3 # contents of source directory
$ cd /media/NTFS2
$ mkdir abc # directory of same name that exists at destination
$ cd abc
$ touch 4 5 6
Now, we have two directories with the same names in each NTFS mount.
Each has some contents (this bug doesn't manifest for empty directories)
=== REPRODUCE BUG ===
1. Open NTFS1 in pcmanfm
2. Right click on directory abc and choose "Cut"
3. Open NTFS2 in pcmanfm
5. When it shows the dialog asking whether to (a) Cancel (b) Skip (c) Overwrite, choose (b) Skip
EXPECTED RESULT : source directory should remain untouched.
ACTUAL RESULT : source directory disappears! (is deleted)
