problem with ooffice from backports

[Marcelo Chiapparini]

Hi!

I am running Lenny in a i386 machine. I have the following line in the
sources.list file:

  deb http://www.backports.org/debian lenny-backports main contrib non-free

After updating the package information, the openoffice.org-style-galaxy
package appears in the following way in synaptic:

openoffice.org-style-galaxy 1:3.2.0-4~bpo50+1

But the openoffice.org and  openoffice.org-style-galaxy packages at
backports are in version 1:3.1.1-15+squeeze1~bpo50+1, the same version is
for the openoffice.org package in synaptic. This mismatch between the
version of openoffice.org-style-galaxy in synaptic and in the backports site
precludes me to install openoffice.org from backports. I commented the
backports line in sources.list, updated the package information, uncommented
again the line and updating the package information again, but the version
of openoffice.org-style-galaxy package in synaptic remains the same wrong
1:3.2.0-4~bpo50+1. The situation is the following:

package
               version
                                                    synaptic
                                         backports.org

openoffice.org                                1:3.1.1-15+squeeze1~bpo50+1
                      1:3.1.1-15+squeeze1~bpo50+1
openoffice.org-style-galaxy              1:3.2.0-4~bpo50+1
                       1:3.1.1-15+squeeze1~bpo50+1



How can I tell synaptic to updated the correct information
regarding openoffice.org-style-galaxy version in order to match the one in
the openoffice.org package? (the same problem with the style-oxygen package)


Thanks in advance
