Bug#661253: recently-used.xbel

[Rain Maker]

I had the same problem too, but after some Googling, 1 of 2 things
seem to be causing these crashes:
- The ~/.nv/GLCache directory holding old caches. Removing this
directory fixes this for some users (not me though)
- Gnome3 searching through .local/share/recently-used.xbel. I emptied
this file and made it immutable (chattr +i). This fixed it for me.

The above does not solve the problem some users have with evolution
segfaulting while receiving mail.

My own syslog told me the process
/usr/lib/gnome-shell/gnome-shell-calendar-server was the process which
was segfaulting. I am not sure, but the combination of
gnome-shell-calendar-server and recently-used.xbel may indicate some
problem in Evolution (more specifically, the interface Gnome3 uses to
search through Evolution), in combination with these new NVidia
drivers, rather then just the NV drivers...
