It is happening on a fresh build of main after #116102 is fixed.

I can reproduce this 100% of times, QueueEmpty as @ericsnowcurrently said in #116102 (comment) never happens to me.

I am on macos.

Seems this behaviour is intentional. Second parameter on get method means default value. So, it's ok to not to see the QueueEmpty exception. But, why is there a tuple as a return value of get? The second item in this tuple looks superfluous (Should there really be a tuple here?)

(Should there really be a tuple here?)

Yes, the tuple is of (default, fmt).

This should be cleared up by gh-116328.

This was fixed in #116328.
