The LibreOffice_3.6.2 rc2 update in QQ proposed repos seems to of low quality.

Two main issues are these:

1. Regression - menus are gone again when using Gnome-shell DE.

2. The LibreOffice crashes immediately when any odt file is opened.

The LibreOffice 3.6.1 rc2 works fine.
So I downgraded back to it.
