Unity Libreoffice

Using LibreOffice unity can not boot from the bar.

This question is unfortunately incomplete and hard to answer. Please be more specific.

Also it seems you want to report a bug in LibreOffice in combination with Unity. If that is the case, please file a bug (with specific information on what you think goes wrong) here:
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+filebug

Addendum: If you want the experimental global menubar integration for LibreOffice, please install the package lo-menubar.

I think he means the following problem: There is no proper integration to the dash-bar of Unity. The general LibO-icon is visible whereas the writer-icon is not visible…?!

Edit:But his question could refer to another problem with unity…

I think there has to be some more work going into Unity integration of LibreOffice
