Additional Information

The reporting user(s) did not provide additional information.

Start in electrum/wallet_db.py, following WalletDB.load_data(), upgrade(), and _convert_wallet_type() from the reported traceback. Reproduce the wallet upgrade path for the reported standard, imported wallet and determine why x/0' is absent. Done means the wallet upgrade no longer crashes with this KeyError.
