Comment # 3 on bug 966739 from Vincent Petry

I noticed a similar issue on my Tumbleweed instance since the last update, that
the mime types for images were not pointing to okular. I thought it was a
mistake so I fixed them by hand in the "File Associations" dialog.

However later on I noticed that okular is not able to open pictures!

okular(15060)/okular (app) Okular::Document::openDocument: No plugin for
mimetype '"image/jpeg"'.

Running "kbuildsycoca4 --noincrement" did not help.

Checking the package contents:
% rpm -ql okular | grep services

It looks like the service files for images are missing ?!
Could be a packaging issue.

If okular did not advertise supporting image files, it might also have affected
mime types. This could potentially be the root cause ?

(let me know if I'm wrong, I can also raise this separately if needed)
