In order to work around this potential bug I do the following at the moment:
- Store: (a) Export the ASCII-armored *secret* key together with its subkeys. (b) Export the ASCII-armored *public* key together with its subkeys.
- Restore: (a) Import the ASCII-armored *public* key together with its subkeys. (b) Import the ASCII-armored *secret* key together with its subkeys.
The actions [1.(b)] and [2.(a)] should not be necessary if there was not this
potential bug.
