Can you reproduce this weird playlist bug???

Question

I see this on Windows 7 and Windows 8.   Spotify desktop app.   Curious if it happens for other people, or on any other platforms.
1. Create a new empty playlist
2. Add six albums each with at least 10 tracks.  I drag and drop the albums to the playlist, one at a time.  You should now have at least 60 tracks in the playlist.
3.  Use the default playlist sorting method,  By that I mean, don't sort the playlist by song, artist, album name, or date.  Should be the order you added the albums.
4.  Scroll to the bottom of the playlist and highlight all of the tracks in the last album.  Select the first track in the album with the mouse and then hold CTRL while you arrow down or mouse click to select the rest of the tracks.
5.  Now drag the selected album up to move the tracks above the second to last album.   You're effectively swapping the bottom two albums in the playlist.
^^^ At this point I get an error message about adding duplicate tracks to the playlist.  Which is strange because I have not added any new tracks, I'm only  reordering them.
6. Now create another new empty playlist.
7.  Select all of the tracks in the first playlist.  CTRL-A works.   And drag and drop them to the new playlist
^^^  Notice the new playlist now has TWO copies of each album!   If the first playlist had 60 tracks, this one has 120!!!
Weird, eh?   Very frustrating when I make playlists of full albums....

I'm afraid I can't. At step 3, when I try to run base within gdb I get no further than the "Database assistant" dialog. Base freezes as soon as the main window is opened when running in gdb.
