.dtrash is empty and full?

[Peter Mc Donough]

Hi,

There is the trash folder in Digikam ".dtrash", which is a nice idea for 
those without KDE.
Presently it is empty, but (!) if I check with dolphin, there are still 
about 250MB of photos.
System Suse Tumbleweed, Digikam 5.2.0

Which settings am I missing?
Alternatively, is there somewhere an option within Digikam for using the 
kde trash folder like in digkam 4.x, or could I simply link .dtash to my 
kde trash folder without causing problems?
