LibreOffice UK thesaurus

[Phil]

Thank you for reading this.

I migrated from another Linux distribution to Kubuntu about two years 
ago and since then I have been unable to get the UK thesaurus going. In 
other words the thesaurus is greyed out under the tools -> languages menu.

I have installed the UK thesaurus using the extension manager and it's 
listed under "Writing aids" as "OpenOffice.org New Thesaurus". I've 
search the Internet for an answer and I see that many people have asked 
the same question.

The thesaurus used to work under my previous Linux installation and it 
does work under Kubuntu if I set the language to "English US"

I was hoping that the 13.10 release might solve the problem. Can anyone 
offer any help?
