bug#15886: 24.3.50; Incorrect window-text-height with non-zero line-spacing

Could you please tell us more precisely what you are doing?  IIUC you
must have set `resize-mini-windows' to nil in order to be able to apply
`set-window-text-height' to the minibuffer window in the first place.
But setting `resize-mini-windows' to t here resizes the mini window
exactly to the height of the text it displays.  So what am I missing?

What is your value of `max-mini-window-height'?
