I see. If I don't get it to work, it will have to wait.

Well, I have a dbgutil build, but it is not enlightening:

  [build CUT] dbaccess_dialog_save
  warn:xmloff.core:29588:1:xmloff/source/core/xmlimp.cxx:851: exception caught
  warn:legacy.osl:29588:1:xmloff/source/core/xmlimp.cxx:852: caught an exception!
  in function:virtual void SvXMLImport::setTargetDocument(const com::sun::star::uno::Reference<com::sun::star::lang::XComponent>&)
  type: com.sun.star.lang.NotInitializedException
  context: N8dbaccess17ODatabaseDocumentE

This one is usual / not a fatal problem: I get it each time I open an
.odb file "normally". I once tried to get rid of it, but never got
anywhere. But the following one, I'm more clueless about:

  warn:legacy.osl:29588:1:dbaccess/source/filter/xml/dbloader2.cxx:519: caught an exception!
  in function:virtual void dbaxml::DBContentLoader::load(const com::sun::star::uno::Reference<com::sun::star::frame::XFrame>&, const rtl::OUString&, const com::sun::star::uno::Sequence<com::sun::star::beans::PropertyValue>&, const com::sun::star::uno::Reference<com::sun::star::frame::XLoadEventListener>&)
  type: com.sun.star.uno.DeploymentException
  message: component context fails to supply service
  com.sun.star.document.DocumentRevisionListPersistence of type
  com.sun.star.document.XDocumentRevisionListPersistence
  context: N4cppu16ComponentContextE

  This used to be an assertion failure: Desktop disposed before terminating it, but nothing bad seems to happen anyway?
  macros_test.cxx:43:Assertion
  Test name: DialogSaveTest::test
  assertion failed
  - Expression: xComponent.is()
  - loading failed:
  file:///home/master/src/libreoffice/workdirs/master/dbaccess/
  qa/extras/testdocuments/testDialogSave.odb

It looks weird that the path is cut in two like that, but I added a
 std::cerr << fileName << std::endl;
and there it comes out without newline; I assume it is the cppunit
stuff that does some word-wrapping.

OK, will commit them.
