Similar error after umount an external usb drive, having 3 of them and an SD card.
This is the first time I can see the log and copy it (the crash just affected the nautilus window); since Natty upgrade I have experienced several crashes but with just a text screen with no option but reboot.
Output from dmesg. I don't know exactly the information to submit, but I hope this log is related to this bug
