insert picture: no preview

Hi,

I’m running LibreOffice 4.1.3 on Debian Wheezy. When I want to insert a picture from file I get a window with a corrupted title (“Insert picture - n**” with * being a square) and although I ticked the “preview” option I get no preview. Inserting does work however.
I am guessing maybe I have something missing, at least some font? Some tool for loading a preview? I did remove some Gnome elements as I don’t use Gnome, nor do I KDE 4, could it be that?

What desktop system / window manager do you use? How did you install LO? I use the same version here under Crunchbang 11 (openbox+XFCE) OK. I install everything e.g., sudo dpkg -i *.deb
