This message is a try to resume the discussion.
Now on another OS - Linux Mint 13 KDE - but with the same version of 
digiKam the problem has arisen again. Unfortunately, "start with a new 
DB from scratch" does not work.

In due time Simon Cropper experimented kindly with one such file 
provided by me. He found out the procedure:

exiv2 extract p1020398.jpg
exiv2 delete p1020398.jpg
exiv2 insert p1020398.jpg

gets the image appeared in digiKam and he suspected the file is somehow 
corrupted.

But command "cmp" shows about this procedure that the initial and final 
versions of the file are identical. Moreover "Reread Metadata" (the last 
item of the Album Menu marked with curved green arrow) results in 
disappearance the image again so it seems to me the problem concerned 
with database interaction.

The point of the problem is unstable behaviour of the program intended 
for professional use. I have about 0.2% of such files but absolutely 
uncertain about which new ones will fill up this collection.

If anybody is going to test this problem I am ready to send such file 
(there are three about 2 MB each) directly to his/her email.
