gnumeric 1.4.3-4_m68k and CORBA error on start

[ljmoore wightman ca]

I'm running Debian Sarge on a Quadra 610; it has 24meg RAM, 750meg 
swap. I've installed gnumeric_1.4.3-4_m68k.deb and its support files.
I have this displayed at starting ... gnumeric & 

** ERROR **: file corba-orb.c: line 360 (CORBA_ORB_init): assertion 
failed: (ORBIT_ALIGNOF_CORBA_DOUBLE > 2)
aborting...


 {repeated down the screen ... }

Any advice on what's happening and what might be done?
Thanks. Larry
