Description Matt Hirsch 2014-07-09 07:44:24 UTC
When copying multiple slides out of a pptx file into a new, empty presentation, under some circumstances, the first slide will be pasted into the new presentation multiple times, rather than a single copy of each of the multiple slides.

Here are the steps to replicate this bug in libreoffice- in Fedora Linux.

1. Obtain the following presentation (created in MS PowerPoint 2010):


2. Open it in impress.
3. Press the new button to obtain a new, blank impress presentation.
4. Select slides 10 and 11 from the pptx presentation.
5. Press ctrl-c or right click in the slide sorter and use the copy context menu to copy the two slides
6. Change to the new, blank presentation window.
7. Press ctrl-v or right click in the slide sorter and select paste to paste in the two slides.
8. Press either yes or no when asked to adapt the format (it doesn't matter which)
9. Note that slide 10 has been copied twice, and slide 11 has not been copied.

This seems to have something to do with slides that are created by duplication in the original powerpoint presentation. In this case, I'm pretty sure slide 11 was created by selecting slide 10 and clicking duplicate slide in powerpoint. Then it was edited.

I have nearly the same probleme in put with ppt/pot Files from PowerPoint 2003 and these Problems can occur in the same Presentation, when coping or duplicating slides, often not the correct ones are copied/duplicated! I have seen this issue in different Versions of LibreOffice the last two years.

Has anyone got an example file they can attach (as an attachment) that triggers this?
Matt's original upload link in comment 2 seems dead, the thing in comment 1 wants me to sign up for a subscription, and neither 5 or 6 supply files!
