dvo->mba: The problem is apparently that copying of an OLE object does not work
(during copying), and as a result the (clipboard) document is in an inconsistent
state. Most unfortunately, there is no low-risk way of aborting the copy
operation at the point of failure, since it is deep down in the sw
infra-structure. Since code in several places assumes the presence of a valid
OLE object ref, I must assume that previously the operation always succeeded,
e.g. by placing a dummy object if the real object cannot be constructed.
Some more details & background: The Writer only ever puts documents in the
clipboard. When copying the 'object', the clipboard will contain a document with
a single, anchored OLE.
The copying itself happens in SwOLENode::MakeCopy(..), which attempts to copy
the object, and then calls the SwOLENode constructore, which in turn creates the
(empty) OLE ref that will later cause problems.
The only real low-risk implementation I can see would be to make sure that the
OLE ref would always contain some kind of object; and some kind of dummy OLE if
the real object can't be constructed.
