Details

Steps to reproduce:

I use Thunderbird 115.8.0 on Debian GNU/Linux 12.

I tried to open an encrypted PGP email sent today by someone I talk to regularly.

Actual results:

Thunderbird does not display email content due to decryption error.

I can open all previous messages of this people (eg. 2024-03-07) but not his new ones.

I tried Thunderbird 115.8.1, beta and daily: same problem.

If I extract the OpenPGP file (msg.asc) from the source, I can read it with « gpg -d ».

Changes in gpg -d -vvv output:
Before:
:literal data packet:
mode b (62), created 1709827228, name="",
raw data: unknown length

After:
:literal data packet:
mode m (6D), created 1709981834, name="",
raw data: unknown length

=> Binary format (b) in old messages versus octet format (m) in new messages.

In Thunderbird GUI (115.8.0):
« There are unknown problems with this encrypted message.

« [init_literal_src() /build/reproducible-path/thunderbird-115.8.0/comm/third_party/rnp/src/librepgp/stream-parse.cpp:1732] unknown data format 109 »

Expected results:

RNP supports octet format (« m ») so thunderbird displays the contents of the email.
