I can reproduce with a master built from today.
I need to enable `debug-on-error', otherwise I only see a minibuffer
message indicating the error, the minibuffer survives.
Lars, be sure to follow the recipe with all details right - no M-x
instead of M-X, not "bro" instead of "brok" etc - then the recipe
"works" for me (and the analysis given by the OP makes sense to me).
HTH,
Michael.
