Description kts 2017-12-28 10:23:18 UTC
I've been seeing this problem since kde plasma 4. Continue seeing it in plasma 5.
I did not take time to report it until now. Now that it'd been reported.
Comment 1 Albert Astals Cid 2018-01-02 00:02:40 UTC
Okular is not resposible for thubmnailing of pdf files in dolphin.

But anyway attach the file, otherwise your bug report is never ever going to be fixed.
Comment 2 Albert Astals Cid 2018-01-02 00:02:53 UTC
waiting for file
Comment 3 kts 2018-01-03 07:43:28 UTC

Fail to show thumbnail in dolphin

There are many PDFs that fail to show thumbnails. I've selected one of them that's small.
Comment 5 kts 2018-01-09 13:44:41 UTC
I've already provided the file in question. Which additional info do you need?
Comment 6 Albert Astals Cid 2018-01-09 21:11:44 UTC
Nothing, Okular is still the wrong product for it as I mentioned.
Comment 7 kts 2018-01-10 08:07:57 UTC
With the file in attachment, you can test that there's no thumbnail. There should be but there's not. What's at false here? Dolphin?
Comment 8 Albert Astals Cid 2018-01-11 23:57:43 UTC
Fixed with https://phabricator.kde.org/D9834

Now needs someone to agree with it

Comment 11 kts 2018-02-08 18:14:02 UTC
The attachment provided showed thumbnail with latest KDE. But some other PDFs did not. I want to email the attachment to someone responsible because it's above 4MB. Who in this list should I sent it to?
Comment 12 Albert Astals Cid 2018-02-09 23:06:46 UTC
I guess you can send it to me, but don't hold your breath on me actually spending much time on something i'm not really maintainer of and neither use.
Comment 13 kts 2018-02-10 09:54:00 UTC
Done sending it.
Comment 14 Albert Astals Cid 2018-02-10 10:16:22 UTC
The problem is that gs doesn't like that file

You probably want to open a bug in https://bugs.ghostscript.com/ and report that gs on that file fails, once that is resolved, the thumbnailer will work.
