Problem dividing circle on intersection in specific drawing

Hi I have problems dividing a circle on intersections with lines in a specific drawing. When trying to click on an intersection (using "snap on intersection") with a line the program says: "Cutting point is not on entity."

When I click on the circle with "snap on entity" selected, dividing the circle works alright.
When I try the same procedure (dividing on intersection) in a "fresh" drawing it works alright.

Can anybody help?
Thanks in advance!
