Hi Renaud,
What do you mean by "default fonts"?
They are the font names that appear in the toolbar when I open a new
presentation and click on the "Click to add text" or "Click to add notes" to
modify a slide, in Normal or Notes view.
Yes, these were the old default fonts for StarOffice, and then
OpenOffice.org - they should however have been removed during OOo 3.3.x
development, if my memory serves me right, so you are correct to query
as to why they should be present in LibreOffice.

You said you created a clean profile from a new user when you installed
LibreOffice - however, did you have any previous OOo or StarOffice
configuration files still laying around on your system ? If so, this
could be one reason why you are still seeing those font entries. Some of
the configuration files are stored system wide, and these are overlaid
on top of the user configuration at startup.
Alternatively, it might be that the default Impress textbox font
configuration setting never got changed to the new Liberation fonts. One
way to check would be to do a search for XCU files, and then see if any
of them contain a reference to Thorndale or Albany.
