Document icons depending on which application opens a document

[probonopd]

The example above may be not the best one, as this may simply be the effect of the VirtualBox FreeBSD package lacking the icons (FreeBSD bug report), which, e.g., Fedora's RPMFusion virtualbox package and http://archive.ubuntu.com/ubuntu/pool/multiverse/v/virtualbox/virtualbox-qt_6.1.6-dfsg-1_amd64.deb make available in /usr/share/icons/hicolor/48x48/mimetypes.

Thanks @[email protected] for pointing this out.

This is the upstream location of these icons:

In this case, the .vbox file wrongly has application/xml as the MIME type. We should also have an EASY way for apps to say that they can-open certain filename extensions.

As pointed out rightfully by @[email protected]:

the same document may be opened by different applications, depending on what you want to do with it. I may want to open an image with the image viewer, if I want to display it, or with an image editor like Gimp or MyPaint. The same for a music file, should it have a Audacious or Audacity icon? A text config file may be used by an application at launch but I may want to edit it with Vim in a terminal or Gedit in GNOME. In those cases, which application icon should the documents have?

The one of the application that gets to open it when the file is double-clicked. For that exact reason!
