Out ot sync was probably not the best wording I have to admit. Out of
sequence would have been better, at least in my case. I'm sorry I was
a bit brief in my first reply, I didn't have that much time... I'm
glad you had some progress though.

I was struggling with the same symptoms last week and in my case it
was the dates of subalbums that was out of sequence.

I have organized my collection like this:
<YEAR>
    <MONTH>
        <DAY>

I found that the <DAY> subalbums was not properly "dated". I.e. some
days was had the wrong date. This made the thumbnails to not show for
all the images even if they were there on disk.

I only use digiKam to create and delete folders, I don't let any other
application do that. I import all images with digiKam which
automatically creates the folder structure. But for some reason, the
date on some albums had the wrong date set.

I also had imported some images twice but to the wrong month in my
case. I.e. some images from September were imported to subalbums to
December. That was an error from my side. The same symptoms was seen
in this case though. Some thumbnails were not shown and there were
large empty areas instead.

Hope I made my findings a bit clearer now!
