Pardon my non-gpg-familiarity, but isn't a "weak key" completely
different from a (maybe) divulged key ?

AFAIK a weak key is a key that, when used, produces a result which is
easier to break than what the cipher promises. In other word, this
would be something specific to this very key, to the value of its
components being poorly chosen, and in no way related to how it was
stored/obfuscated itself.

IOW, isn't this specific key one of the identified blowfish weak keys
classes ?

Meaning not only this key, but anything it signed and/or was encrypted
for (I did not check which one is affected), may be considered
compromised ?
