view story

https://bbs.archlinux.org – Hello,please excuse my bad english.I have a problem. Since the libreoffice update from 3.5.6 to libreoffice don't start. For a short time i see the splash-screen and that's it. In the terminal, when i type soffice or lowriter or libreoffice --writer i can't see any message. Also i deleted the ~/.config/libreoffice folder. But that doesn't help. These packages are installed: libreoffice-common libreoffice-gnome libreoffice-de libreoffice-writer libreoffice-calc. When i downgrade to 3.5.6 everything is fine. I have a laptop with openbox and a desktop-pc with gnome. Sa (HowTos)
