Comment 99 for bug 1021375

I'm on 17.04 fully updated as at 30/5/2017. This is still happening. As per everything the OP had in 2012, I can confirm the same at this end.

No remounting or editing of permissions changed nautilus' permissions for me except for:

* Closing nautilus,
* Removing ~/.config/nautilus, *1
* logging out and back in again (for good measure—not a reboot) and
* restarting nautilus worked for me

*1 May not have been required, but done because I was working through several posts and it was one of the suggested solutions
