Gtksheet cursor movement

My results programme uses gtksheet and is working well on this machine (Debian 
Lenny AMD64) but when I compile it to run on a 32 bit machine (Debian Squeeze) 
I find that it crashes when you cursor down populated cells, generally with 
either 'invalid pointer' or 'corrupted double linked chain'. Backtraces, when 
you get them, have a nest of libc6 calls.

So I tried compiling testgtksheet and blow me the same thing happens. So it's 
not entirely me.

Is there a solution to this, I'd like to distribute the prog, including a 
Windows version.
