Bug 443406

Created attachment 303139 [details]
screenshot of icons looking bad (default theme)

Sometimes it also says

Could not open location 'gphoto2://[usb:001,009]/'
The default action does not support this protocol.

I'm pretty sure the problem is that several bits of Nautilus are trying to mount
it at the same time. Nautilus or gvfs probably needs some way of saying that a
mount request is already outstanding.

Can't help with this unless you tell what the extension of these files are.
Also, instead, please provide output of gvfs-info.

That's a bug with the gio plug-in for GStreamer, see

http://bugzilla.gnome.org/show_bug.cgi?id=526794

Btw, I think you are also suffering from bug 435413. Once the ACL snafu is
sorted out I'll get a new gphoto2 package into F9 and Rawhide.

The extensions are .alb and I'm using the default Fedora theme.

I have noticed that

only appears when trying to open the player via Places. When I open it via
Places -> Computer, I never suffer the same error (but the first error mentioned
appears sometimes, though).

Unfortunately we can't sniff the files in the gphoto2 backend because of a
limitation in libgphoto2 (can only read whole files at once so performance would
be devastating) so we have to rely on file extensions unless the device itself
gives us a mime type (it is capable of that but most devices are dumb).

However, we ought to fall back to application/octet-stream for it and Nautilus
ought to present a nicer icon. What's the output of gvfs-info for one of these
files?

That's bug 443085.

David, I noticed that ancient-looking icon at an other place: On my desktop with
a file with .desktop ending. 

It's a shortcut which defines Icon=geogebra.png whereas geogebra.png does not
exist in /usr/share/xxxx. Instead of showing some nice and polished looking 
global icon, it also shows that GNOME 0.5 (:P) icon. gvfs-info as follows:


$  gvfs-info GeoGebra.desktop

Should I report a seperate bug report for the icons? Against which components
should I file it?

I just tried to use my MTP player, but now I get:


DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply
(timeout by message bus)

and after some time I can access it, and no files are being displayed in
Nautilus, but the amount of free space is correctly displayed.

David, do you have an idea why it does not show any files on my music player
anymore?

gvfs-info is this:

$ gvfs-info gphoto2://[usb:002,005]/
display name: SanDisk Corp. Sansa E200 series (mtp)

Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:

Works fine now. If I experience some problems with MTP, I will report a seperate
bug report again. gvfs update fixes the icon issue.
