Description Jeremy Bicha 2016-09-08 23:26:12 UTC 
I tried to open a sample .cbz [1] in gnome-books 3.21.91 with tracker 1.9-1 and shared-mime-info 1.7-1 on Ubuntu GNOME 16.10 Beta. But instead I get this error:

Oops! Unable to load "Adekab-v01c01"
File type Zip archive (application/zip) is not supported.

==========

Here's some commands I ran in a terminal:
$ file Adekan-v01c01.cbz 
Adekan-v01c01.cbz: Zip archive data, at least v2.0 to extract
$ mimetype Adekan-v01c01.cbz 
Adekan-v01c01.cbz: application/vnd.comicbook+zip
$ tracker info Adekan-v01c01.cbz 

  'rdf:type' = 'http://www.w3.org/2000/01/rdf-schema#Resource'
  'rdf:type' = 'http://www.semanticdesktop.org/ontologies/2007/01/19/nie#DataObject'
  'rdf:type' = 'http://www.semanticdesktop.org/ontologies/2007/01/19/nie#InformationElement'
  'rdf:type' = 'http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#FileDataObject'
  'nie:mimeType' = 'application/vnd.comicbook+zip'

(extra lines removed)

Downgrading to shared-mime-info 1.6-1ubuntu2 fixes the issue.

The mime-type is application/vnd.comicbook+zip. See:

tracker no longer has this line (and related lines) for the file:

'rdf:type' = 'http://www.semanticdesktop.org/ontologies/2007/03/22/nfo#EBook'

I'm commenting here since I don't know whether that needs to be fixed in shared-mime-info or in tracker.

Looks like tracker doesn't use aliases.

The mime-type changed from application/x-cbz to application/vnd.comicbook+zip, but the alias application/x-cbz was added to keep the backwards compatibility. Tracker doesn't seem to use the aliases.
