[SOLVED] X server segfault after exiting

Question

The X server on my machine always crashes with a segfault generated by a Fatal IO Error 11, when I exit from an X session. Otherwise works perfectly fine. So this really has no apparent impact on my ability to use X. I'm just curious what may be generating this segfault and what I can do to fix it.
This is the report while X is running (startx):
(EE) Failed to load module "vmwgfx" (module does not exist, 0)
(EE) vmware: Please ignore the above warnings about not being able to to load module/driver vmwgfx
error setting MTRR (base = 0xd0000000, size = 0x01130000, type = 1) Inappropriate ioctl for device (25)
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning: Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
> Ignoring extra symbols
Errors from xkbcomp are not fatal to the X server
cp: cannot stat `/usr/share/lxde/pcmanfm/pcmanfm.conf': No such file or directory
GuestApp: no value for option 'unity.desktop.backgroundColor'
** (pcmanfm:3974): DEBUG: unable to load icon system-software-install
(pcmanfm:3974): Gtk-WARNING **: Radio group does not contain an action with value '0'
This is the actual segfault when I exit my X session:
** (lxsession-logout:4166): WARNING **: dbus-interface.c:71: DBUS: The name org.freedesktop.Hal was not provided by any .service files
** (lxsession-logout:4166): WARNING **: dbus-interface.c:71: DBUS: The name org.freedesktop.Hal was not provided by any .service files
** (pcmanfm:4158): DEBUG: icon theme changed!
waiting for X server to shut down XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"

And before I installed LXDE I'd exit with 'exit' on the last term window.
So you exit, it crashes - can you restart it?
