Frédéric COIFFIER
https://bugs.kde.org/show_bug.cgi?id=337502

            Bug ID: 337502
           Summary: No preview in the tumbbar
           Product: digikam
           Version: 4.1.0
          Hardware: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Preview
          Assignee: [hidden email]
          Reporter: [hidden email]

In preview mode (F3), if the thumbbar is shown (Settings | Show Thumbbar), this
one contains only blank squares (except the star score) : no thumbnail, no
filename...
Moreover, the thumbbar height cannot be reduced.

Please remove thumbs DB (or rename it) and rebuild all... Just to check.

Q: Do you turn on HQ thumb option ?

I removed thumbs DB (and rebuilt it) but it doesn't change anything. (Moreover,
thumbs are correctly displayed in the Thumbnails view).

Where can I find the HQ thumb option ?

No, this option ("Use large thumbnail size...") was disabled.

But enabling it solves the problem : thumbnails are now displayed in the
preview mode.

If I disable the "Use large thumbnail size" option, the problem is back.

Gilles, do you reproduce this problem ? Or do you need more information ?

When this option is enabled or disables, thumb database must be re-initialized.
You must recompute all thumbs from your collection.

And no, i cannot reproduce the problem here...

I also have this problem (v 4.1, under Debian with GNOME).

When trying to show the thumbnails in the preview mode, I get this error
message in the console:

digikam(6864)/digikam (core): ThumbnailLoadThread::load: Thumbnail size  315
is larger than  256 . Refusing to load.

Like Frederick, enabling high-quality thumbnails "solved" the problem
(presumably because the maximum thumbnail size is now larger than 256).
Reverting to normal thumbnail sizes brought back the problem. Rebuilding
thumbnails didn't work. The reason for the large thumbnail size (315) is
presumably because the thumbnail bar is too high but, like Frederick, I can't
make it smaller (only larger).

There may be some connection to the surrounding environment. This used to work,
but stopped working a while ago in connection with me doing a normal aptitude
upgrade. I remember that there was no digikam update at the time, but there
were a bunch of GNOME updates (and other stuff). I can't say exactly what or
when though, unfortunately :/. It may be another clue though, perhaps.

--- Comment #8 from Frédéric COIFFIER <[hidden email]> ---
As a workaround, deleting the following lines in ~/.kde4/share/config/digikamrc
(when Digikam doesnt' run) solves the problem (but it reappears after some
times) :
ThumbbarState=AAAA/wAAAAD9AAAA....

It's really strange that the Thumbbar cannot be reduced....

I also have the blank thumbnail problem in Preview mode ( Fedora / Gnome /
Digikam 4.6.0 ). Deleting ThumbbarState in the rc file fixes it for me.

I can confirm that the thumb bar cannot be reduced. This problem also exists in
the Light Table, as well as Preview mode. In Light Table, the thumb bar is not
as big as in Preview mode, but it is still too big, making the Light Table not
very useful.

--- Comment #11 from Gilles Caulier <[hidden email]> ---
I closed a file recently about the thumbnail DB item updated which call a wrong
SQL command : date and thumbnail ID are inverted in table...

You can imagine the sideeffect.

Please look if bug #345025 closed with next digiKam 4.9.0 fix this issue.

--- Comment #13 from digikam phan <[hidden email]> ---
I had this on a new install and [partly] solved it by setting colour management
to the same [in my case to Adobe, the second-most common]  If I remember,
previous versions did not have colour management [CM] on by default, thus
side-stepping any such 'issues'. In my experience the CM adjustment [of any
graphic app] can result in a mess, so I too had avoided them..

I say partly as I am still unable to adjust the thumb-bar size to my
preference...
I think this is most probably a consequence of applying CM without redrawing
every image on demand.

I see this bug is still live so if this is still an issue why not try switching
CM off and work from there.
As such I'm not sure if it's a bug per se.

(and switching between these two modes brought up the thumbnails without a DB
delete, for me)
