Hi Puma,

Thanks for reporting.

I can't reproduce the issue with a pptx at hand in version 5.1.4.2 (5.1.6.2 will be released soon) and a daily build.

Can you add your test file please?
Ciao - Cor

Created attachment 128104 [details]
pptx file for testing

This is one of the files producing the error
Comment 3 Cor Nouws 2016-10-20 20:04:05 UTC
thanks - interesting - I can confirm the issue with that file.

Needs checking for dupes and regression
Comment 4 jebsolutions 2016-10-21 22:46:31 UTC
The way libreoffice handles duplicate slide *names* has bugs.  

In attachment 128104 [details] all the slides are named something like "Linearis optimaizalas".  

You can confirm this by right-clicking on any slide in the slide sorter on the left and select "rename slide".

I think under the hood it is really starting the slideshow from the first slide with the same *slide name* as the currently selected slide name.  i.e. it's not saying "start on slide 4" it's saying start on slide "Linearis optimaizalas". Since all the slides have the same name, the first slide that matches that name is always slide #1.  

I notice that newer versions of libreoffice prevent you from renaming a slide to the same name as an existing slide.  It greys out the save button with no explanation to the user as to why you can't choose that name.

Interestingly if I duplicate a slide (e.g. the 6th slide) it will give it a name "Slide 7".  Fine...but if I try to rename one of the "Linearis optimaizalas" slides as "Slide 8" (even though there is no slide with this name) it prevents it as well.  But...if I duplicate the "Side 7" slide...guess what, it creates the new slide name as "Slide 8".  

I am getting deja vu of past crashes.  Often after duplicating a slide, doing basic edits, and then saving.  Maybe a clever dev can check if this mis-handling of duplicate slide names has problems elsewhere in the code.

Please don't "hijack" a bugtracker and open a brand new one.
Indeed, your description is unrelated to this one except the fact it concerns slideshow.
Comment 6 Aron Budea 2016-11-08 04:20:04 UTC
Julien, comment 4 adds some very good observations about this issue, it's not  hijacking at all.

Issue reproduced with as early as 4.1.0.4 / Windows 7 (in earlier versions there's no Start from current slide option).
Comment 7 Julien Nabet 2016-11-08 06:10:59 UTC
You're right Aron. Re reading comment 4, it could explain the pb indeed.
Sorry for my previous comment Jebsolutions.
Comment 8 Yousuf Philips (jay) (retired) 2016-11-09 13:08:28 UTC
So the problem boils down to the import code not making sure that slide titles it is using as the slide names is unique, as pptx dont support slide names. It should either import the slide without slide names, like it does for ppt files, or it should import them like so.
