Provided info by Axel Krebs:
¨My digiKam database was quite large- 140000 pics, 6,9 GB size(!!). As I
knew I have to work intensively with that database, I created a
selection of only 8000 pics to gain some loading speed.

Instead of getting smaller after some loadings, it kept this size and
loading "speed".

After some weeks, I included all other pics, I had outsourced before.

In "digiKam settings ->  collections" I added those pics by selecting a
(sub-)directory, which are stored in a number of directories.

No I got problems: while tags had been set up hierarchical before, they
look meshed up now. Have a look at tags "auto" and "quasimodo" in
enclosed pic.

As the structure was correct before, I am quite sure that the internal
structure of database might be corrupt.¨


##############################################################
Start trying reproduce according info supplied by Axel Krebs
##############################################################

I start making a copy of my db containing my art collection.
digikamdb 229 MB
thumbnails 4,9 GB
number of picture 136043
number of albums 5567
number of tags 1248
startuptime 145 seconds. second startup 98 sec.

    This looks from the quantitative perspective more or less comparible setup

I put the NEF in one of the art folders
It opens normal
add some tags
it still opens normal with image editor and with gimp
add another tag
every thing still normal

Now I go removing albums, but it appears that I can not remove a
subalbum(directory) without actually deleting it.
So I have to make a second root album ¨ARTtest¨
Move several subalbums to ¨ARTtest¨ and remove my main root album ¨ART¨ from
settings->etc
I close dk
reopen digikam

digikamdb 229 MB
thumbnails 3,8 GB (This is changed but much larger than expected)
number of picture 29635
startuptime 20 sec (this is different from Axel´s experience)

Now I add under settings->configure dk etc several subalbums that formerly has
been under the rootalbum ¨ART¨ to the new ¨ARTtmp¨

I can not detect any changes in tag structure
Tags in NEF are still as before
NEF can still be opened normaly.


Axel, what do you think I should do differently to reproduce the problems?

I wonder about a few things that maybe could be related.
Can there be something wrong with harddrive?
Did you test db integrety as I suggested?

Will be happy to do further investigations if I only had a clue how to went on.

Can a corrupted db be due to corrupting NEF? Does someone know the answer?
