I updated to digikam 4.6.0, no change
I run
	sqlite3 -line digikam4.db 'pragma integrity_check;'  and
	sqlite3 -line thumbnails-digikam.db 'pragma integrity_check;'
no errors
	sqlite3 -line digikam4.db 'vacuum;'
reduced size about 50%
	sqlite3 -line thumbnails-digikam.db 'vacuum;'
no vivible change in file size

however the thumbs of those images are still not shown.

There must be something in those images that digikam does not like 
(although they were produced with digikams batch tool). They wouldn't be 
shown in any other folder, no matter if I rename them. But when I open 
the fiole with gewenview and save a new copy, it is immediately shown...

I can send such an image to a developper, but not publish it...
