I'd suggest running memtest86+ on your computer overnight or over a weekend; there are crashes from chrome, chromium-browser, gdb, software-center, apport-gtk, apt-check, oneconf-service. While many of the errors were in apt's libraries, making me suspect hard drive corruption there, that wouldn't explain all of them. So it might also be RAM.

Good luck.
