We are using the xdg mime database, the mimetypes.xml file contained
in activities is added to that database. So that's the mechanism
through which activities can associate icons to mime types.

In a python shell inside strace -e open:

>>> gio.content_type_get_icon('image/png')
open("/home/tomeu/.local/share//mime/mime.cache", O_RDONLY|O_LARGEFILE) = 3
open("/home/tomeu/sugar-jhbuild/install/share/mime/mime.cache",
O_RDONLY|O_LARGEFILE) = 3
open("/usr/share/mime/mime.cache", O_RDONLY|O_LARGEFILE) = 3
open("/usr/local/share//mime/aliases", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
open("/usr/local/share//mime/subclasses", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
open("/usr/local/share//mime/icons", O_RDONLY|O_LARGEFILE) = -1 ENOENT
(No such file or directory)
open("/usr/local/share//mime/generic-icons", O_RDONLY|O_LARGEFILE) =
-1 ENOENT (No such file or directory)
open("/usr/share//mime/mime.cache", O_RDONLY|O_LARGEFILE) = 3
open("/usr/share/gdm//mime/aliases", O_RDONLY|O_LARGEFILE) = -1 ENOENT
(No such file or directory)
open("/usr/share/gdm//mime/subclasses", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
open("/usr/share/gdm//mime/icons", O_RDONLY|O_LARGEFILE) = -1 ENOENT
(No such file or directory)
open("/usr/share/gdm//mime/generic-icons", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
