nautilus crashed with SIGSEGV in g_type_check_instance_cast()

[David Richter]

eror occured twice same scenario - latest updates loaded in between errors
a) connected Kindle 2 device
b) recognised device (note this has not occured previously - device previously not recognised at all that I could determine)
c) initiated Calibre (note - not sure whether Calibre has anything to do with crash)
d) device no longer recognised by either Calibre or system

Seems there may be a problem with USB devices from previous errors - however you must be making progress as this is the first time that 12.04 has recognised the Kindle 2 devcie at all

Keep up the good work

Using Dell 6410 - latest bios updated
12.04 LTS - latest updates loaded (as of 29 Feb 2012)

Calibre updates direct via Calibre site (not via repository)
