you're right. Then this is a bug in the implementation, according to
the comment in the extensions site the core implementation should do the
same:

Update: Sven Jacobi from Oracle did a native implementation of this
dialog for OOo. It will be available for OOo 3.4. So starting from OOo
3.4 this extension will no longer be needed.
http://extensions.services.openoffice.org/project/EnhancedGraphicExportDialogs
(to get that page I had to refresh the browser several times, but it
seems still online).

I tried to find a link to the extension source code, but could find it.
It may be interesting to look what the extensions does, it uses UNO API,
so it can obviously be done in the core implementation.

I'm CCing Christian Lippka, may be he has still the code and can share it.
