matrix operations in 1.2.10

[Allin Cottrell <cottrell wfu edu>]

I'm tryint to invert a 2x2 matrix in gnumeric 1.2.10.  I enter the
formula

=minverse(C3:D4)

and press Ctrl-Shift-Enter.  I get a scalar result, and the
auto-generated formula bar entry reads

{=minverse(C3:D4)}(1,1)[0][0]
                   ^^^

What am I (or what is gnumeric) doing wrong?

C3:D4 contains

2  4
1  3
