Additional Information

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

Start in electrum/storage.py at WalletStorage.load_data and get, then follow the loading path from electrum/daemon.py. Reproduce the Android-reported failure with a malformed wallet file and verify that opening it no longer raises the shown AttributeError.
