Another reason for this might be that the key has been retrieved from
a keyserver and the keyserver removed the (encryption) subkeys due to
a bug.  I get quite often mails that it is not possible to send me an
encrypted mail due to a missing encryption subkey.  When the sender
retrieves the key by other means (e.g. X-Request-PGP: mail header) it
does work.
