            Bug ID: 308310
          Severity: major
           Version: 2.9.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: No thumbnails are created in the album view,
                    rebuilding thumbnails doesn't work
    Classification: Unclassified
                OS: MS Windows
          Reporter: [hidden email]
          Hardware: MS Windows
            Status: UNCONFIRMED
         Component: Thumbnails
           Product: digikam

There are no thumbnails. The album-tree is shown, although sometimes digikam
tells me there are 0 pictures in the albums, and sometimes it shows the correct
number of pictures. Either way, no thumbnails. If I choose "rebuild
thumbnails", nothing happens.
I saw some thumbnails once, but only in one album, shortly after they
disappeared for good.

Reproducible: Always

Steps to Reproduce:
1.Open digikam
2.hope that it doesn't crash (which happens from time to time)
3.it opens correctly, but shows no thumbnails


Expected Results:  
it should have shown thumbnails

WinXP SP3, library with about 16.000 pictures

I'd like to add: The pictures are saved on external usb harddisc. digiKam
2.8.0. showed the same bug as 2.9.0.

It shows no entries (empty view) or no thumbnails (view with n entries, each
having a rectangle, filename/rating/tags display as you like, but empty space
where the thumbnail of the picture should be)?

It shows no entries - nothing. Only the albums are shown correctly on the left
side, with the number of the pictures each album contains in brackets. On the
right there is nothing, no jpgs, no tiffs, no raw files, no
rectangles/filenames/ratings/tags.
Sorry for the late reply, I'll try to pay more attention to my mails...

This is typically a problem with the ioslaves, installation, finding and
starting them by the KDE runtime.

So it is a problem only the KDE people could solve?

Git commit 57b269e2d6dfd8f0c11d482ec12d3e9c126c1cd1 by Ananta Palani.
Committed on 03/02/2013 at 23:04.
Pushed by palani into branch 'master'.

Fix thumbnails not shown in Windows and excessive use of virtual memory /
handles which may cause crashes and other unexpected behavior by removing file
monitoring and only monitoring directories for changes. These problems might
still occur with very large numbers of folders but could not be confirmed.
However, medium to large collections should no longer cause a problem.

I have made a beta compilation of digiKam 3.0.0 for you to test whether the
commit I just made fixes your problem:

Can you give it a try and let me know how it works for you?

I have been having the missing thumbnails problem for quite some time now and have tried multiple versions of Digikam.  The 3.0 beta you posted solved my problem!!

Thanks!
