Please see the attached screenshot. This happens after I switch to map and back or to GEO location and back. Reproducible: Always

There is something wrong with KDE Kio slave interface. Job are started and broken for an obscure reason. Thumbnail are process in a separated process trough KIO slave. This is why thumb are empty. Sound like a problem with KDE core, not digiKam. Just to test, run Showfoto and open a folder with images. Look if thumb are visible in thumbbar. Showfoto do not use kioslave... Gilles Caulier
Created attachment 72186 [details] showfoto screenshot showing missing thumbnails showFoto also has problem with thumbnails. See screenshot.

If you run dolphin with icon view mode through a folder where images are stored, do you see thumbnails properly ? Gilles Caulier
dolphin thumbnails (with preview on) work fine. gwenview thumbnails also work fine.
Which libpgf you use ? Go to Help/Component Info for details. libpgf is used to created compressed thumbnails. Gilles Caulier
LibPGF: 6.11.42 - internal library
ok. it's fine. Do you compiled digiKam yourself or do you use a pre-compiled package ? Do you use sqlite or mysql database ? If you remove thumbnails-digikam.db file from your database folder, and you restart digiKam, it's fix the problem ? Gilles Caulier
I compiled the FreeBSD port myself. I chose mysql database option before compiling. Removing thumbnails-digikam.db doesn't help the problem.
1 / Please switch to sqlite to see if it's a thumbs DB problem under freeBSD 2/ If it doens't help, i suspect a libpgf port problem under freeBSD. With cmake use "-DENABLE_THUMBS_DB=off" to disable thumbnails DB and use fredesktop rules based on PNG thumbs (less faster and huge space disk)... Gilles Caulier
1. switching to sqlite didn't help. 2. with cmake use "-DENABLE_THUMBS_DB=off" thumbnails show fine. I reported this issue to FreeBSD maintainers: kde@freebsd.org
Ok. That i suspected about libpgf. If you want t investigate more, look into digikam/tests, there are 3 small command line tools to check libpgf. One is qtpgftest. create a small test.png image and copy it in same dir than qtpgftest. Run this one : it will save it as pgf and look if it can load it in reverse. It will do the same with JPG and PNG codec and print conversion time to compare. If all is fine, you must see no error on the console and test.pgf must be created. You can load it with showfoto so see if image is valid. If something go wrong, there is libpgf port failure under FreeBSD. You ust report this problem to PGF team... Gilles Caulier
There is a similar report in the Red Hat Bugzilla for Fedora 17 (Digikam 2.6.0) on https://bugzilla.redhat.com/show_bug.cgi?id=836953 .
the fedora downstream report in comment #16 seems to imply the problem is in libgphoto2-2.4.14
To Rex from comment #17 : there is no relation between libgphoto2 and digiKam thumbnail interface... Yuri, Please, give use a fresh feedback to see if this entry still valid using last digiKam 3.5.0. Thanks in advance Gilles Caulier
Yurl, this file still valid using last digiKam 4.2.0 ? Gilles Caulier
New digiKam 4.11.0 is available : https://www.digikam.org/node/740 Can you reproduce the problem with this release ? Gilles Caulier
digiKam 4.12.0 is out : https://www.digikam.org/node/741 We need a fresh feedback using this release please... Thanks in advance.
Will provide feedback once will install this version.
With digiKam 5.0.0, this problem is not reproducible. I close this file now. Don't hesitate to re-open if necessary. Gilles Caulier
