Numerous Empty Categories

[Lonnie Lee Best]

I suspect it is already known that many of the categories list no corresponding software. For example:

Probably a side-effect of the appstream data not showing all the available apps, but we should probably hide empty categories.

[Sebastien Bacher (seb128)]

is that still an issue with the recent updates?

[Lonnie Lee Best (launchpad-startport)]

Recent updates show no categories at all:

Now the categories are back, but some are still empty. Here's an example of an empty one:

where is k3b? I find it only writing the name in the search text on top, but not in any category.

[Robert Ancell (robert-ancell)]

According the the appstream data for k3b, it has the following categories:

Categories:
  - KDE
  - Qt
  - AudioVideo
  - DiscBurning
  - System
  - Filesystem

I can see it in System>All and System>Filesystem.

For comparison, Brasero has:

Categories:
  - GTK
  - GNOME
  - AudioVideo
  - Audio
  - Video
  - DiscBurning

I think it is the lack of the "Audio" and "Video" categories in k3b that is causing not so show in those categories.

I've opened bug 1558346 about the k3b issue.

Currently I see no empty categories, even if many of them have only 1-3 packages listed
