This is normal when you have switched away of the active minibuffer
with "C-x o" or something similar.  The "[Quit]" message (in brackets)
is a telltale sign that the minibuffer is active and waiting for you
to finish some interaction.

However, if you can show a recipe to reproduce this, we could be sure.
