[Users] Encrypted mail received as "encrypted.asc" and not decoded

[Paul Rolland (=?UTF-8?B?44Od44O844Or44O744Ot44Op44Oz?=)]

Hello,

One person I'm working with is sending me mails which are encrypted using
my PGP key.
When received, this mails are containing two attachments:
1 - PGPMIME Versions Identification application/pgp-encrypted
2 - encrypted.asc application/octet-stream

If I save the "encrypted.asc" and process it with: gpg -d < encrypted.asc,
gpg asks the password associated with my key and decodes perfectly the
message.

But it seems that Claws is unable to do the same, and I can't figure out
why.
I've loaded:
PGP/Core
PGP/Inline
PGP/MIME
S/MIME

I've tried unloading PGP/Inline or S/MIME but got no luck with that.
Some extracts from the message itself that may help :

If I select the first attachment and "Display as text", it displays:
Version: 1

If I do the same with the second attachment, I have:
-----BEGIN PGP MESSAGE-----
Comment: GPGTools - https://gpgtools.org

hQEOA+U12I/yhzUMEAQAgMxkEyqf+q00MZ1LvPb8WIuYc37hQ3vYOc14QaHaJaQc
...
-----END PGP MESSAGE-----

Any idea ?

Paul
