Bluescreen after installing libreoffice from app manager

I have installed the following software in a fresh Reactos 0.4.7 installation in virtualbox: Firefox, VLC, the AC97 driver  and Libreoffice. In the middle of the installation of the latter, reactos bluescreened and after, the system won't boot anymore, any boot attempt ends in a bluescreen. I am not sure how useful the screenshot is. If needed (and given instructions) I could generate more detailed debugging output (I have already enabled the vbox debugger but I am not sure what to do with it.)
