I have packages libreoffice-help-en-gb and libreoffice-help-en-us installed.
LibreOffice 3.4.4 OOO340m1 (Build:402)
pre-installed on Ubuntu Oneiric
Here is the screen shot.
Error message: No topics found
I think it related to JRE because I run a live cd ubuntu and found that it showed a message saying that "this feature requires Java Runtime Environment", but I have JRE 6 installed on my current distribution (not the live cd version) , or maybe it needs JRE 7?
