Looks fixed to me. :-) (reported a duplicate of this bug)

Not sure why it only happens with my camera. The bug does not occur with
other USB devices including flash drives. Can it be related to shotwell?

No, I don't think so. Please update and see if the crash is fixed with the
latest unity package.

The dupe I reported was because it was happening when trying to mount
network (sftp) shares via nautilus, at which it absolutely consistently
failed until this fix; I can also confirm I had no such problems even
before the recently-released fix on connecting and mounting usb drives
of various shapes including a brand new kindle, and firewire and raid
volumes were also fine.

I wonder if you're having a problem with one particular device if it
might not be a separate bug related to that hardware? Also, you didn't
say whether this fix made the problem go away. :-)

@omer @Rachel : I will let you later because I don't have the devices with
me at work. I have not updated since last night ( Vancouver BC time).
