Error calling StartServiceByName for org.gtk.vfs.GPhoto2VolumeMonitor

[jeffsmonteiro]

Describe the bug

After installing gphoto2, on my PC using Ubuntu 18.04 LTS, when I try to use some Gnome Applications, including Nautilus, I get the following error and the Gnome Apps has a large delay to launch:

_Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.GPhoto2VolumeMonitor: Timeout was reached (g-io-error-quark, 24)

After purge gphoto2 the problem persist.

After reinstall gphoto2, the problem back:
"Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.GPhoto2VolumeMonitor: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.gtk.vfs.GPhoto2VolumeMonitor': timed out (service_start_timeout=120000ms) (g-dbus-error-quark, 20)"

Do you have many images on your cameras SD card?

Does "gphoto2 -L" take very long?

Its probably more a GNOME gvfs bug than a gphoto2 bug I think.

Do you have many images on your cameras SD card?
The SD card is empty.

Does "gphoto2 -L" take very long?
Nope

it is important to comment that the problem occurs even if I am not using the camera or gphoto2.

Nautilus or any other Gnome application that depends on opening or writing files, suffers from this problem. After removing the services commented on in the mini-tutorial informed in the bug description, the problems simply stopped occurring.

we did not have any other reports of such delays so far... weird.
