Bug#912304: dolphin: Missing thumbnails/previews without kio-extras-data

[Charles Huber <genpfault@gmail.com>]

Package: dolphin
Version: 4:18.08.0-1
Severity: normal

Dear Maintainer,

2-3 months ago thumbnails/previews were working fine (images had thumbnails, videos had thumbnails, etc.) in Dolphin.

Then sometime in the past couple of weeks after the usual upgrade they just...stopped displaying.  The Preferences -> General -> Previews list was also empty.

Installing 'kio-extras-data' fixed the issue for me.
