Here's the problem.

OD 1.1f13. ODF 1. I've tweaked FW_CODPart::CloneInto and
FW_CODPart::ClonePartInfo to support promises when Rapid-I Button is
embedded and it's a single frame being dragged or copied or cut. Due
primarily to the incredible speed of AppleScript :-), it takes about 1.8
seconds to externalize a Rapid-I Button, so I want to avoid actually doing
it unless absolutely necessary.

Using ODF Container, I embed a Rapid-I Button. Then, I copy select the
button and copy it. With my modifications, this causes the
FW_CDataInterchange object to record a clipboard promise. Next, I delete
the button with the "delete" key. Since delete is undoable, I'm not
expecting FW_CODPart::ReleaseAll to be called yet for the button. Then I
save the document. Now, I expect ReleaseAll to be called, but it is not.
Finally, I try to paste, and crash because my promise is no good and was
not fulfilled before the original part was clobbered.

Is this an ODF problem or an OpenDoc 1.1f13 problem or an ODF Container
problem?
