Steps to reproduce the problem:

• Select a subject from SubjectManagement, and right-click the name of subject.
• Select "Siirrä roskakoriin"
• Confirm "deletion" by clicking OK at the next window.

Attached error should appear, and nothing is moved to trash.

I don't know if final deletion ("Tyhjennä roskakori") works, because I have not been able to move anything there.

Btw, what's with the mixed finnish-english in the buttons and menus??
