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.
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.
waiting for file
ok, I'll email you the file.
Created attachment 109642 [details] Fail to show thumbnail in dolphin There are many PDFs that fail to show thumbnails. I've selected one of them that's small.
I've already provided the file in question. Which additional info do you need?
Nothing, Okular is still the wrong product for it as I mentioned.
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?
Fixed with https://phabricator.kde.org/D9834 Now needs someone to agree with it

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?
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.
Done sending it.
