Cannot read newsgroups with new Thunderbird
After a recent Thunderbird upgrade in Buster (from version 91-something
to 101-something, or like), it stopped handling newsgroups properly
(where the source is News Server (NNTP) on the same machine, and there
nothing was changed/upgraded).
To be precise, Thunderbird now seems downloading new messages from the
NNTP server, then shows the new number of messages in the folder pane,
but displays an empty content in the message pane, i.e. Subject and From
columns are empty, while Date column is filled with 1/1/70 - for all
news messages that arrived since the Thunderbird upgrade.
Btw, handling personal emails (from the local POP Mail Server) is ok.
