Comment 3 for bug 147819

The preview of OOo files is as far as I know not included in a default ubuntu-install. For previewing OOo-files, the scripts which are enabeling the preview are reading the /Thumbnails/thumbnail.png file embedded in every open-document file (which in fact is a zip-archive). When you are opening a given odt file e.g. with file-roller, you can see that this is related to the embedded graphic-file. So I don't think this is really a bug, at least not a "bug" which can be fixed in the ubuntu-distribution.
