Yes, I had a similar message after another update of LM14 Xfce(32) today, except it was a /var/lib file that seemed to go pear-shaped.
I started in recovery mode several times until it hit the auto fsck @ 20 [which is quicker than using another liveCD].
startx provided a root log-in from where I reset all my Xfce Settings, everything was set back to defaults, plus a bunch of other tidying up after checking that everything was still present, etc. (It was!)
Logged out, rebooted and b-i-n-g-o.
If all else fails, recommend loading Puppy Wary or Slacko, then extract all your personal stuff onto mobile HD, USB stick, w.h.y. before re-installing. Sometimes just copying /home onto media will suffice for some folks. The only app. that regularly goes bad is Claws - sometimes it will destroy you addressbook, sometimes your 'sent' folder, so be sure to copy these regularly to another device or, at least, partition.
