Opening a volume that is not mounted fails

[Olivier Tilloy]

Binary package hint: unity

If nautilus is not launched when the session is started, removable devices won’t auto-mount.
Plugging in a removable device will append an icon in the launcher, but clicking this icon will fail to open the file manager to browse this device.

The reason is that the code for open_volume() in places-volume-child-controller.vala calls the asynchronous method to mount the volume but doesn’t wait for it to complete before trying to open up the URI for the volume.

To reproduce, one should make sure that nautilus is not launched when the session is started by removing 'filemanager' from the GConf key /desktop/gnome/session/required_components_list.

The attached patch solves the problem by monitoring the mounts added and continuing the open operation once the volume is mounted.

Note that I’m not fluent in Vala and as you can see I couldn’t find a way to connect a callback to the volume.mount.begin(…) method, so I had to work around it by monitoring all mount added signals and matching the volume against the volume being mounted. Suggestions on how to achieve this in a more elegant manner are welcome.

lets make sure this makes it into upicek as well as we won't be autotarting nautilus. for some reason I couldn't "also affects" upicek.

We count on nautilus being launched at startup, either with the "run without windows" mode or when it's drawing the desktop.

It will be fixed in Natty as nautilus will be started automatically. I think Maverick users of unity-2d ppa can live with that bug too until we make that version use nautilus automatically too.
