Gentlemen, this is a -batch job.
Suddenly I'm getting
"Window height 3 too small (after splitting)"
However none of my equipment has windows even twice as small.
Something must have broke recently.

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.

Indeed,
$ emacs -batch -eval \
	'(progn(bbdb "." t)(other-window 1))'
...Window height 3 too small (after splitting)

mr> You could also try to replace "progn" by "let ((window-min-height 1))"

Phew, that worked. Thanks.

This seems to indicate that some bbdb function doesn't respect
`window-min-height'.  You might want to get back to the maintainers of
bbdb.
