LibreOffice problem - TDE / KDE File Picker !?

Hello all, Today I installed two versions of LO (4.3.4 at first, 4.2.7 later) on openSUSE+TDE 3.5.13.2 ; I have 4.2.5 running with no problem on a similar setup (albeit on another hardware). The problem is that when I try to install extensions LO freezes. I first thought it might be a problem of the latest version, that's why I tried 4.2.x, but no change. I then tried running it as root, same thing. In the end I read the crash message better (when it announced the install dialog had terminated) and noticed it talked about "KDE File Picker". I do have the basic components of KDE 4 installed (pulled in by some dependencies) but not the DE. I switched back to XFCE, started LO and installed the extensions with no problem. Back in TDE I can use the extensions. So this File Picker the culprit. Obviously LO can "see" when "KDE" is running, and uses another "file picker" if not. Is it trying to run a KDE 4 element under TDE, and crashed? Is it trying to use some TDE software but does not manage it? Maybe when everything is renamed "TDE" this sort of situation will be easier to debug. Thinking about my workaround, I remembered a setup point in options/general that offers to "Use LibreOffice dialogue boxes". Selecting that cures the problem. But it does not tell me if this is a TDE or KDE issue. Thierry
