Behaviour of kvault

SUMMARY
I created a kvault using kgpg and inside it I have a subfolder. When I open the vault, zip the subfolder and then encrypt it with kgpg, after encryption I cannot close kvault (without forcing it) because it says that kgpg is blocking the closing of the kvault. If I close manually kgpg and then try to close the kvault, then it works. 

STEPS TO REPRODUCE
1. open a kvault (with kgpg) that contains subfolders in it (once opened);
2. compress one of the above mentioned subfolder;
3. encrypt the compressed file with kgpg with a symmetric key;
4. after encryption, close all your windows (so you are sure that Dolphin is not concerned in blocking the closing of the kvault);
5. block the kvault (in the system tray there is the button "Block kvault");

OBSERVED RESULT
It can't close the kvault because "kgpg is using the kvault", even after having finished the encryption.

EXPECTED RESULT
The kvault closes because I have no jobs open that deal with the kvault.
