Zip archive that contains pptx file and same odp file

After opening .pptx file (exported from Google Drive Presentation web app) I can't move slide if it has title shared with another slide. (I mean it was 2 or more slides with same title, but different content). 
Both Ctrl-X - Ctrl-V and Drag-n-drop doesn't work as expected. Changing slide titles after importing doesn't help. 
Moreover, after I save this file in ODF, restart Libre Office and open this new .odp it still doesn't work as expected and reproduces this strange buggly behaviour. Attaching exported Google Drive .pptx and file saved as .odp. Try just swap first slide and second - you will get just duplicates of first slide. (If it will reproducable on your environment. Mine is Ubuntu 13.04, Libre Office (build ID: 400m0(Build:2))) Note averything is ok when moving third slide.

I didn't download this package manually, I just use ubuntu and make updates regulary. I've just tried to reinstall it from repository, and behaviour doesn't change.
UPDATE: Just noticed that bug I've described happens only when moving second slide to first position, not vice-versa. 
Attached an screencast

Yeah I suspect it's Ubuntu specific and thus NOTOURBUG, I was able to move things around no problem. Bjoern will have more info when he gets a chance to comment. Thanks for the additional testing

reproducable on both a Ubuntu release build and on master at https://gerrit.libreoffice.org/gitweb?p=core.git;a=commit;h=26d092b3635680248f8b176564409e6c0c24bfbf (dev-build) and (different distro build. definitively not Ubuntu specific.
Comment 7 Joel Madero 2013-05-17 19:13:21 UTC
strange. Will try again then attempt a bibisect on it.
Comment 8 Joel Madero 2013-05-19 16:59:48 UTC
Well, I can confirm but I can confirm more than just this. 

The same problem happens with the odt file. 

Also, it goes all the way back to prebibisect times (

Updating version & title (removing pptx) as it happens no matter what the extension is.

Only regressions should use the keyword 'preBibisect'. Removing it...
Comment 11 Xisco Faulí 2016-09-14 15:43:12 UTC
[This is an automatic message]

Changing version to in order to get rid of 'preBibisect' version as looks to be the last version not covered by bibisect-43all.
Comment 12 Justin L 2016-12-27 17:55:32 UTC
reproduced on Windows with LO x32 - marking as not Linux only.
reproduced on Ubuntu x64 with LO 5.3beta2 - marking as not x32 only.
Comment 13 Justin L 2016-12-28 19:32:41 UTC
If you move a duplicately named slide (not the first one, but any following ones) to ANY location, it will be replaced by the first instance of that name.

Not really high/major importance any more, since it is difficult (if not impossible) to rename a slide to match an existing one now.

Still, proposed fix at https://gerrit.libreoffice.org/32481
