Check m_internals in UnregisterValidationInterface
When a wallet is created it is registered in the validation interface (in CWallet::CreateWalletFromFile) but it is not immediately added to the wallets list. If a shutdown is requested before AddWallet (case more evident when -rescan is set) then m_internals can be released (in Shutdown -> UnregisterBackgroundSignalScheduler) before the wallet and then ReleaseWallet would call UnregisterValidationInterface with m_internals already released.
