I think this is due to a lifetime issue with the debugger's UI callbacks. DebuggerUI::DebuggerUI calls DebuggerController::SetDebuggerUICallbacks and passes a pointer stored in m_uiCallbacks. DebuggerUI::~DebuggerUI deletes that object, but nothing unregisters the callbacks from the DebuggerController. I'm not sure what, if anything prevents the DebuggerController from making a UI callback after the DebuggerUI goes away.
