The problem was resolved by a sharp-eyed developer on the ooo-user list.
The result of 4 is correct.
2+i2 is 2 (because cell i2 is either empty or 0)
2-i2 is 2 (same reason).
(This is because Calc allows simplified direct references to cells.)
The result is 4.
Try =IMPRODUCT("2+2i";"2-2i");
or =IMPRODUCT(COMPLEX(2,2);COMPLEX(2,-2))
etc.
In OpenFormula, There is no direct notation for complex numbers as a numerical
form. Text is used to convey the notation in a way that is distinct in those
places where complex operands are allowed for. There does not appear to be any
reasonable way around this in Calc.

I confirm this result with 3.5.4.2, Ubuntu 12.04
