Mail composer does not support channels. Indeed as it can be used to post a message or send an email it only supports partners. Previously field channel_ids given to the composer was used only in website_forum. However it is not used and therefore simplest way of solving it is to remove it. Anyway allowing to have channels followers of forum tags and being notified of new publications is probably more spammy than really necessary. Especially that it never worked.
