KDE trash can showing full with nothing in it.

[Thaidog]

For some reason my desktop trash can shows that it has files in it but when you open it there are no files to empty.

If you try to empty it the trash can still shows files in it.

I can not even drag a file to it! either I try to put something in to it but the mouse goes to a cross sign that says I can not put anything in it!

Is there some way to reset this?
