I have installed the latest version of libreoffice a while ago and I just updated ubuntu 12.04. When I opened the libreoffice document, the text in the globalmenu is missing and you only see the highlight color selecteing the menu where the text would be.
The only way I found to deal with this bug for now is to remove the following packages:
sudo apt-get remove libreoffice-gnome libreoffice-gtk libreoffice-gtk3
The menu will look like a Windows 95 app, but it shows.
Exactly the same problem here, after doing an update just an hour ago. Tried deleting my user profile and also uninstalling,
apt-get autoclean and reinstalling, but nothing seems to work. It still doesn't work when I install the Spanish language pack, which I hoped might restore the texts.
UPDATED: This seems to be the same as reported in question 297743, which was closed as it corresponds to a bug report.
sudo apt-get remove libreoffice-gtk
