Sentry Crash Report:

Description Kubuntiac 2010-04-18 22:20:27 UTC 
Version:           1.4 (using KDE 4.4.2)
OS:                Linux
Installed from:    Ubuntu Packages

Basically, Dolphin doesn't show font previews for me.

I have "fonts" checked in the preview tab (in both Dolphin and Konqueror). I have the preview button at the top of the window turned on. The fonts are well under the max file size. Instead Dolphin just shows the generic "T" or "A" font icons.

I'm on Kubuntu Lucid AMD 64 using kde 4.4.2.
Comment 1 FiNeX 2010-08-01 15:52:18 UTC 
Cannot reproduce using KDE SC 4.4.5
Comment 2 Kubuntiac 2010-08-01 17:53:37 UTC 
Ah, it only seems to be happening via fonts:/
Comment 3 FiNeX 2010-08-02 15:59:22 UTC 
Ok, I confirm that :-)
Comment 4 Jekyll Wu 2011-07-09 12:07:10 UTC 
confirmed on 4.6.90
Comment 5 Alejandro Nova 2011-12-07 11:47:59 UTC 
Confirmed on Dolphin 1.99. This is strange.
Comment 6 Jeroen van Meeuwen (Kolab Systems) 2012-08-24 16:18:33 UTC 
Resetting assignee to default as per bug #305719
Comment 7 Marco Zühlke 2014-01-06 23:40:06 UTC 
Confirmed using using dolphin 4.12.0 on Kubuntu.
Comment 8 Frank Reininghaus 2014-01-08 10:39:01 UTC 
The same problem occurs when viewing fonts: with FolderView (whereas viewing the actual file: location where the font files are stored works fine), so it seems that this is not a Dolphin issue.

[PreviewJob] Also pass along that we're the thumbnailer when stat'ing file

Enables the KIO to react differently when being stat'd by the thumbnail KIO slave

Comment 10 Patrick Silva 2019-03-09 14:23:43 UTC 
why is this report still open?
Comment 11 Christoph Feck 2019-03-24 11:18:26 UTC 
Let's assume Patrick confirmed it's fixed by Kai's commit.
Comment 12 Patrick Silva 2019-03-24 12:07:40 UTC 
It's not fixed. Preview works in /usr/share/fonts but it does not when I open fonts:/

Operating System: Arch Linux 
KDE Plasma Version: 5.15.3
KDE Frameworks Version: 5.56.0
Qt Version: 5.12.2
Comment 13 Christoph Feck 2019-03-24 13:28:04 UTC 
Thanks for the update; it seems I misunderstood comment #10.

kio_fonts: fix the thumbnails creation by tweaking the USEntry fields

- Set the fancy name, e.g. "Foo, Bold Italic", as UDS_DISPLAY_NAME
- Set the actual file name, e.g. foo-bold.ttf, as UDS_NAME
- Set the actual file url, e.g. /usr/share/fonts/truetype/foo-bold.ttf as UDS_URL

Setting the UDS_URL fixes font thumbnail creation when using kio_fonts.
And IIUC, also avoids calling get() on "font:/" urls, the files are already
local; setting the UDS_URL makes all the font previews work on my system
at least.
FIXED-IN: 5.23
