(hm, I thought I asked this before but I can't find it)

Under what circumstances will this failure occur?

Why do we emit a message at all? What action can the user take upon
seeing the message?

Do we have a Fixes: for this?

From the info provided thus far I'm unable to determine whether a
-stable backport is needed. What are your thoughts on this?
