Put two resistors and connect them in the pcb view
Double-click the ratsnest line between the resistors in schematic view.
Pull off the schematic wire off of one of the resistors.
Delete the wire in pcb view.
Result: A ratsnest line appears between the resistors in pcb view (but not in breadboard view). This bug does not always happen, so one might have to try a few times.
Expected Behaviour
There should be no ratsnest line since the resistors are not connected in any view.
Hint: Deleting the pulled-off schematic wire and then undoing the Delete, fixes the problem, i.e. the ratsnest line in pcb view disappears.
Current Behaviour
Build: Fritzing 1.0.1 and before
