Breakpoint in JS expression of a ListView delegate while item is removed lets application crash

Reproduction:

• Create a QAIM that can be filled/erased over slots.
• Create a QML file that shows a ListView of the model.
• Add a JS expression to the delegate component (like onClick handler) and set a breakpoint in it
• add a item to the model
• trigger the breakpointin that item
• remove the list item from another thread over queued signal/slot-connection
• continue from the breakpoint
