The default value of `window-min-height' is 4 and since 3 < 4
`split-window' throws that error.  The error can occur independently of
the height of the window you want to split: If the window you want to
split has 50 lines and you want to split it into two windows of size 47
and 3 you get the error.

Not very recently, I suppose.

I don't have bbdb so I can't test this.  Can you verify whether the
error occurs in `bbdb-display-all-records-completely' by omitting all
clauses following the (other-window 1) clause?

You could also try to replace "progn" by "let ((window-min-height 1))"
but this will probably fail if the function calling `split-window' uses
the value of `window-min-height' for calculating the size of the new
window.
