Comment 8 for bug 824466

I think I might have discovered the 'guilty' packages causing the controls of the Presenter Console not being displayed.
At first, I was shocked to learn that even when I installed the 3.4.4 packages from LO's website on Ubuntu 11.10, the issue still remained.
I then started looking (with the help of Synaptic) for any remaining packages which had any reference to libreoffice and which were coming from the Ubuntu repo's.

Turns out that even while I expected to be rid of all LO packages when removing any package starting with 'libreoffice', there are still other packages which don't have 'libreoffice' in their name, but still influence the behaviour of LO (luckily this is mentioned in their description). The suspect here is the "Libreoffice UNO runtime environment". Removing all packages related to this environment and then re-installing the packages from the LO site fixed the problem!

The packages provided on the LO website ship with their own version of the UNO runtime environment (exact package name is libreoffice3.4-ure).
Without having any extensive knowledge on packaging it's kind of weird to be suggesting this, but perhaps there should be some kind of 'conflicts' dependency (?) added to either of these packages, so Ubuntu's version of the UNO environment automatically gets removed when libreoffice3.4-ure is installed?
