I don’t know if this will help but recently I discovered I had two versions of LibreOffice installed on my system. I’m using Tumbleweed and after I updated to version 4.4.3, I discovered that there were still some 4.4.2 packages installed including the main libreoffice package.
Definitely. If Xorg suddenly crashes, it’s often an issue with the graphics driver.
What card do you have? Maybe you could try to install the propietary fglrx driver. The latest Beta should work fine on Tumbleweed if you install it with Sebastian Siebert’s latest script: https://www.sebastian-siebert.de/
Forgot to mention, I use an AMD A4-5100 APU with HD8670M.
Well, switching to fglrx might prove problematic, since Tumbleweed has never kernel versions and all, incompatible with the Catalyst driver ( even with Sebastian Siebert’s version, if I’m not mistaken), and to be honest, I’d rather avoid it if possible, since it’s quite buggy. Hopefully, it will get fixed soon, since it’s quite annoying.
