+++ This bug was initially created as a clone of Bug #258775 +++

Version:           1.5.0 (using KDE 4.5.3) 
OS:                Linux

I have two collections defined:
- 1 on my local HDD
- 1 on my NAS (Collection on Network Share)

Here's the problem:

- Move one folder from one collection to another collection
- Folder and content are now visible in the destination collection
- Folder and content thumbnails still visible in the original collection !
- Physically, the files have been moved (they're in the destination collection
and no longer in the original one)

- Pressing F5 doesn't fix it
- Rescanning the collections doesn't fix it

- Closing digikam, relaunching it still shows the folder and thumbnails in the
original collection
- Rescaning the collections now makes the folder disappear from the original
collection

Reproducible: Always

Steps to Reproduce:
- Move one folder from one collection to another collection

Actual Results:  
- Folder and content are now visible in the destination collection
- Folder and content thumbnails still visible in the original collection !
- Physically, the files have been moved (they're in the destination collection
and no longer in the original one)

Expected Results:  
Folder and content should be visible only in the destination collection

It was working fine in 1.2.0
It started happening when Fedora upgraded digikam from 1.2.0 to 1.5.0

It's DANGEROUS because you might think the files are still in the source collection ! and if you happen to delete the ones visible in the destination collection then you actually lose your files !!!!!!
