1.5.1- devel. installer fail

[Eugene <communique@xxxxxxxxxxxxx>]

Hello All.

I've tried to install a system from 1.5.1-Devel iso-image 
(LATEST-Devel.iso.bz2, 07-Mar-2006). After creating subpartitions 
installer fails when trying to transfer files to new filesystem with the 
message:

Added 30 total items to copy source table
dfuibe_installer in free():error:chunk is already free
pid 682 (dfuibe installer), uid 0: exited on signal 6 (core dumped).

Anyway, system installing process continued 'by hand' got it up.
Digging up a core file made no additional info for me.
Sorry for stupid question, if there was a principal change between DF1.4 
and DF1.5 in the installer or what can be the matter?
