Bug 1063239

Can you run
XDG_UTILS_DEBUG_LEVEL=5 xdg-mime query default application/x-virt-viewer 
in the working case and non-working ssh case and paste the result here?

I tried with a ssh -X to my local machine and this worked as expected.

ssh:
# XDG_UTILS_DEBUG_LEVEL=5 xdg-mime query default application/x-virt-viewer
Checking /usr/local/share//applications/defaults.list
Checking /usr/local/share//applications/defaults.list
Checking /usr/share//applications/defaults.list
Checking /usr/share//applications/defaults.list
 Checking /usr/share//applications/remote-viewer.desktop
   Select /usr/share//applications/remote-viewer.desktop [ -1 => 0 ]
remote-viewer.desktop
# xdg-open console.vv

Result:
open with gedit


non ssh:
# XDG_UTILS_DEBUG_LEVEL=5 xdg-mime query default application/x-virt-viewer
Running KDE trader query "application/x-virt-viewer" mimetype and "Application" servicetype
remote-viewer.desktop
# xdg-open console.vv

Result:
open with remote-viewer

Pleease also run XDG_UTILS_DEBUG_LEVEL=5 xdg-open console.vv in both case.
It seems to me that remote-viewer is properly associated with .vv files, but that xdg-open is misbehaving somehow through ssh.

SSH:
# XDG_UTILS_DEGUG_LEVEL=5 xdg-open console.vv 
START /usr/bin/gedit "console.vv"

** (gedit:6232): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-SPCRH4ZwLD: Connection refused

Result:
open the vv file with gedit


non-SSH:
# XDG_UTILS_DEBUG_LEVEL=5 xdg-open console.vv 
Selected DE kde

Result:
can connect the guest with remote-viewer

I think if you run
XDG_CURRENT_DESKTOP=KDE  xdg-open console.vv 
things will work through ssh. At this point this really is an xdg-mime or system setup issue than an issue with this bug fix imo.

Did you run "XDG_UTILS_DEGUG_LEVEL=5 xdg-open console.vv" or ""XDG_UTILS_DEBUG_LEVEL=5 xdg-open console.vv" ? (DEGUG vs DEBUG) You put the 2 versions in your latest comment, and I think using _DEBUG_ would give more output. 
Alternatively, you can run sh -x /usr/bin/xdg-open console.vv

Sorry for the typo.
As you said it's not an issue of virt-viewer, should I file a new xdg-mime bug?

SSH:

1. # XDG_CURRENT_DESKTOP=KDE  xdg-open console.vv

Thanks for the additional testing! You can file an xdg-mime bug, but it's possible that it's the best it can do on your system. On my system it manages to detect a GNOME desktop even over ssh, it uses gvfs-info to get the file mime type (on yours it uses 'file'). These differences cause xdg-mime to use gedit in the end on your system.

Moving the bug back to ON_QA as per comment #8

Hmm, seems I'm confused about the state of this bug, seems the fix was not added to the rhel7 .spec file yet, moving back to NEW.

Moving the bug to POST, the patch from comment #0 must be added to the RHEL package.

Which will happen automatically when we rebase to 0.6.0

codong file a bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1122447

Christophe Fergeau, thanks for your help and suggestion.

With following verify steps, i can move this bug to verified.
package version:
virt-viewer-0.6.0-3.el7.x86_64

verify steps:
non-ssh 
1. Download the vv file
2. # xdg-open console.vv
The console.vv file opened with remote-viewer successfully.

over-ssh
1.Download the vv file
2.# xdg-open console.vv
The console.vv file opened with gedit.
this is the same issue with bug bug 1122447.

Try with KDE:
# XDG_CURRENT_DESKTOP=KDE  xdg-open console.vv
The console.vv file opened with remote-viewer successfully.

Try with GNOME:
# XDG_CURRENT_DESKTOP=GNOME  xdg-open console.vv
The console.vv file opened with remote-viewer successfully.

and confirmed with Christophe Fergeau about above steps, that's enough to verify this bug.
