GnuCash unstable 1.5.6 does not start up

[Richard -Gilligan- Uschold]

I just updated my 1.5.5 to the latest unstable: 1.5.6

cvs -d :pserver:cvs@cvs.gnucash.org:/home/cvs/cvsroot login
cvs -z3 -d:pserver:cvs@cvs.gnucash.org:/home/cvs/cvsroot update -dP

Compile it without guppi:
./autogen.sh --enable-opt-style-install --disable-guppi
--prefix=/opt5.6  > & autogen.err.txt
make >& make.err.txt
make install > make.install.txt
chmod -R o+rX /opt5.6

It compiled with no errors.

I get the following error when I run it:

This is a development version. It may or may not work.
Report bugs and other problems to gnucash-devel@gnucash.org.
The last stable version was gnucash-1.4.11.
The next stable version will be gnucash-1.6.0.
