Bug Description

Binary package hint: rhythmbox

In jaunty alpha 6, my creative zen vision :M 30g is automatically mounted by gvfs when plugged in. Accordingly, GNOME ask what to do when I plug the device and the only choice is rhythmbox, however when opening rhythmbox (with mtp plugin enabled), the device does not appear anywhere. When launched in a terminal, rhythmbox prints : "LIBMTP PANIC: Unable to initialize device"

Rhythmbox is only able to detect and use the device if I open it while the device is NOT mounted by gvfs.

rhythmbox : 0.12.0-0ubuntu1
gvfs : 1.2.0-0ubuntu1
libmtp8 : 0.3.0-1ubuntu3

This is/was part of another bug that I was having regarding the same problem. Problem is that gphoto/gvfs shouldn't be grabbing hold of the Zen players.

Looking at the 'mounted' Zen. It shows it's properties as a gphoto2 filesystem. Once again, the issue seems to be that gphoto2 is mounting the Zen, which it should not be doing. It's not a camera or camera device. It can handle pictures, but only for viewing, and is easily loaded through Gnomad2.

I'm back to the 'double mount', where the Zen is mounted by the filesystem, and just as it releases, is remounted by gphoto2. It's then locked (docked) to the system through gphoto, and becomes unavailable for the programs that work with it - Gnomad2, and Rhythmbox. Until I manually(through desktop) go in and unmount, the Zen can't work with the programs that it's supposed to. Once unmounted it seems to work as expected, I haven't noticed any other problems other than this mount/gphoto2 issue.

So the gphoto error is gone, but gphoto should not be grabbing hold of the Zen player.

S*

I build rhythmbox in my PPA with this patch included. Since I don't have a MTP device anymore, can someone test it and give feedback if the patch fixes the issue?

En mi caso el reproductor mtp que falla al momento en que rhythmbox intenta abrirlo es un teléfono celular Samsung SGH-F250L, en modo mtp.
