"Open in File Manager" is not working

[Olivier Croquette]

Hi,

A quick hint for those who would have the same problem. I just had the
issue that "Open in File Manager" was not working. More exactly, it was
opening the Videos app of Gnome (Totem), which just showed an error
message.
Since digiKam ist just using the desktop settings I checked there:

$ xdg-mime query default inode/directory
ART.desktop

Weird! I had expected Totem there. I use Gnome, so I tried:

$ gio mime inode/directory
Default application for “inode/directory”: org.gnome.Totem.desktop
Registered applications:
	org.gnome.Totem.desktop
	vlc.desktop
	ART.desktop
	org.gnome.Nautilus.desktop
Recommended applications:
	org.gnome.Totem.desktop
	vlc.desktop
	ART.desktop
	org.gnome.Nautilus.desktop


Bingo. Then:

$ gio mime inode/directory org.gnome.Nautilus.desktop
Set org.gnome.Nautilus.desktop as the default for inode/directory

Double check:

$ gio mime inode/directory
Default application for “inode/directory”: org.gnome.Nautilus.desktop
Registered applications:
	org.gnome.Totem.desktop
	vlc.desktop
	org.gnome.Nautilus.desktop
	ART.desktop
Recommended applications:
	org.gnome.Totem.desktop
	vlc.desktop
	org.gnome.Nautilus.desktop
	ART.desktop


Now the output of xdg-mime is correct too:

$ xdg-mime query default inode/directory
org.gnome.Nautilus.desktop

And "Open in File Manager" is working again. So I am happy, but I would
be even happier if I understood how xdg-mime and gio relate to each
other, technically speaking. Some general info can found here:

It would be also nice if the file was selected in the file manager,
instead of just opening the directory.

Best regards
Olivier
