You've got multiple segmentation violation errors in your system logs; this many of them for seemingly random programs makes me think you may have corrupted data on your hard drive or failing memory or other hardware issues.
Run debsums -as (as root) to see if program files are known to be corrupted.
Run memtest86 or memtest86+ overnight to see if your memory is bad. (A clean run overnight isn't proof that things are alright, but failures mean you have problems that need to be resolved.)
