Error received when exporting

I am attempting to export a Powerpoint PPTX file that has all of the slides hidden.
I get a "General input/output error" (screenshot attached).

I originally experienced this attempting to convert the PPTX to PDF using unoconv.
The error I received when doing that was:

Input file: /tmp/presentation.pptx
unoconv: UnoException during export phase:
Unable to store document to file:///tmp/presentation.pdf (ErrCode 3088)

If I add at least one non-hidden slide, or use the "-e ExportHiddenSlides=true" flag to unoconv, the export succeeds.

My use case for this is that I am converting uploaded PPTX files to PDF automatically, so I have no control over the content of the file and cannot simply unhide the slides.

Comment 5 Timur 2019-10-16 09:41:39 UTC
Version where behavior started should be correct before setting bibisectRequest.
No repro LO 3.4. because there was no separate option "Export hidden pages". 
Repro LO 3.5 and 3.6 and 6.4+.
This is a minor issue with the workaround. I'd rather call this enhancement, just to change general error message to an informative message. 
I wouldn't call this a regression since that's a new useful feature by Pierre-André Jacquod as written in https://wiki.documentfoundation.org/ReleaseNotes/3.5.

Dear gfairbanks,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
