Thunderbird 91.2 on Fedora 35: Error logged every time a message is selected by mouse or by up/down keyboard

I'm on Fedora 35 64bit, using Thunderbird 91.2, installed through Fedora Repo. I have two imap accounts, + a gmail account on it. Thunderbird works fine but every time I select a message with the mouse or with moving up & down with the keyboard, the following two entries are logged. Not that this causes any problems, but it just annoys me seeing these errors. My system log is constantly filled with these enties.

I newly upgraded from Fedora 34 to 35. I don't really know if these errors existed or not before upgrade.

Nov 04 13:51:33 alpha mozilla-thunderbird.desktop[2831]: IPDL protocol error: Handler returned error code! Nov 04 13:51:33 alpha mozilla-thunderbird.desktop[2831]: ###!!! [Parent][DispatchAsyncMessage] Error: PClientManager::Msg_ForgetFutureClientSource Processing error: message was deserialized, but the handler returned false (indicating failure)

Any suggestions?

I see the same thing on Gentoo running 91.7.0.

Every time I click on a message in the message list pane causing it to be displayed in the message pane, I see two of those error messages. The first one happens immediately, the second one is delayed by a second or two.

I have a single account configured, and it is using the OWL plugin to talk to an Exchange server.
