Research direction
Read electrum/gui/qt/wizard/wallet.py around lines 739 and 752, then follow the calls from wizard.py lines 149 and 217. Reproduce the wallet-wizard choice flow represented by the reports and identify why a value is None before subscripting. Done means the reported flow no longer raises this TypeError.
