Thumbnail view, wrong file is moved

[chincherpa]

Hello,
I have just sorted pictures while the following misbehaviour occurred:

Testscenario:
thumbnail view (MDBU is active (on file icons as well))
A folder containing 1 folder, 2 files
1 File is selected
Drag the other (not selected) file into the folder
The selected file is moved

[admin]

Confirmed. Fix comes.
