Created attachment 183373 [details]
expanded

SUMMARY
In the album tree view the item count of the parent folder (in my attached example "2015") is showing 0 when the folder is expanded. 

STEPS TO REPRODUCE
1. Make sure the checkbox is activated (I am posting the German names, as I am not 100% if my English translation is correct):
settings -> digikam setup ("Digikam einrichten") -> Views ("Ansichten") -> Tree view ("Baumansichten") -> Show number of items in all tree views (Anzahl der Einträge in allen Baumansichten anzeigen) 
2. View an album in the album tree view sidebar with subfolders while collapsed. It should show a number if the subfolders have items.
3. Expand one album in the album tree view sidebar with subfolders. It should now show 0 while the subfolders do have items.

OBSERVED RESULT
When expanded the parent folder shows 0

EXPECTED RESULT
should still show the same number (1444 in my case)
