Status changed to 'Confirmed' because the bug affects multiple users.

[San (san-plusnet)]

Maybe bluetooth mount?
Not sure too...

[Alessandro Rinaldi (s-ale-p)]

It happened to me.
Steps:
- I opened an ISO with Mount archives
- It mounted (it appeared on the left bar of a Nautilus window)
- I didn't access it (I mounted it by mistake instead of burning it), but I unmounted it immediately whit the "Eject" button from the Nautilus left bar
- It said "Can't unmount..." and then the error appeared.

[CydeSwype (ircone)]

mine happened when i was connected to a remote host (sftp). server went down so the mount became unavailable. almost immediately, gvfs threw this error

[Vasily (piatachki)]

Right!

It was when i begin connect to ftp via nautilus

[Alexey (alexeyza)]

In my case it happend when I unmounted an SMB connection to a windows7 machine.
Everything worked fine, but when I've finished working and I used nautilus to unmount it threw this error.

[Marcos (marc-lledo)]

Reguards, when i umount a iso file then crash
