Description fabien.michel 2013-02-07 15:49:54 UTC
Created attachment 74354 [details]
Sample file

This document was created from MS Office.
I've extracted a problematic page in the attached document.
When the page is showed to screen, LibO become very slow.

The bug comes from the image.
The original file format of image was a png.

The workaround is to extract image from document (right click > save image) and reimport it in place.

This happen on MacOS 10.5 and 10.7 with Libreoffice and LibreOffice 4.0 beta.

Same on ~AMD64 Gentoo with LO

It seems to happen also with documents created in LO, as indicated by Bug 78529
