Update!!

Sorry it's taken me so long to get around to looking into this, but I finally
have the exact problem:

An album will not display if the total number of folders/subfolders below it
(and including itself) is >= 1000.

This is reproducible every time for me.
Others should be able to reproduce it by creating a folder with 1000 subfolders
(attached script may help, comments on the script are welcome too! - run with

`./makeLotsOfDirs "/path/to/testingDirectory"`

)

Place any digikam-compatible image file(s) in any subfolder(s), and add the
folder as an album in digikam. Select the album root and turn on 'Include Album
Sub-Tree'.
No images are displayed.
Delete 2 or more subfolders and refresh the digikam view...
The image(s) is/are displayed.
Try adding more subfolders again, refresh the digikam view...
No images are displayed once the total number of folders/subfolders in the
album is >= 1000.

Now, why this should happen (and why 1000, not 1024), I don't know. Anyone more
familiar with the workings of digikam care to take a guess?

Here's hoping this helps on the way to fixing it!

Rob
