"Operation not supported by backend" while getting photos from camera

The situation is as follows:
I'm trying to copy photos from camera using a file manager (thunar in this case). The attempt fails with a message "Operation not supported by backend".

Configuration:

• uname: Linux xxx 3.9.6-1-ARCH #1 SMP PREEMPT Fri Jun 14 08:12:55 CEST 2013 x86_64 GNU/Linux

• libgphoto2 2.5.2-1

• gphoto2 2.5.2-1

• gvfs 1.16.3-1

• gvfs-gphoto2 1.16.3-1

• thunar 1.6.3-1

• mount info for this case:
  gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,relatime,user_id=1000,group_id=100)

What is known:

• Everything was fine on 2013/06/13 - I was performing successfull copying operation on the day.

• The exactly same message started to appear on a different machine running Arch, with both unupdated Nautilus from 2.x line and latest pcmanfm. No other machines were tested.

• Only copying and moving files/directories via file manager doesn't work. I can browse the camera and delete files and directories with no problems.

• I can copy the files using cp (via gvfs mount).

• I can grab the files using gphoto2 from command line.

• Applications are able to open the files with no problems (via gvfs mount).

• Downgrading gvfs, gvfs-gphoto2, gphoto2 and libgphoto2 to versions from before 2013/06/13 doesn't fix the issue.

• Logs are clear.

First I suspected that something is wrong with gvfs or libgphoto2, but I'm able to use them with no problems, as long as I don't try to copy a file via file manager. This could mean something is wrong with the file manager, but the issue suddenly affected three different file managers on two independent machines. And the logs remain silent. I have no idea how to deal with the issue.

Hello
I have the same problem in xfce but found a usable workaround:
Don't mount the camera or unmount it if it's already mounted, open Shotwell and just import the photos. No error messages, no permission problem.

Usable workaround, not requiring additional tools, was posted in the first post: use cp on mounted partition or gphoto2. The problem is not how to retrieve the files, as this is obvious, but how to copy them using file manager or how to trace source of the problem.

Stupid me. Yes, you mentioned that. Sorry.

gtkam from the AUR worked for me.

Looks like it the same problem as described below. I was able to trace it to g_file_copy call using ltrace.

Something wrong with dbus daemon

Thanks for the reply.
I have other problems those I think are related to dbus (shutdown, sleep and restart by systemctl), i'll try to investigate.

I have the same problem.
I just installed ArchLinux, but there is also the same kind of problem on Debian since several months (couldn't do anything from Nautilus, but Shotwell was working).
I assume it's a problem with dbus...
