We are having this same issue. Until reading this post I had not fully realized that it happens only for dimensions to doors, and only after using the publisher to save DWG files.
Basically a handful of dimensions end up linked to the origin instead of to the door axis. (Other end of dimension string is linked to a gridline)
Going forward we will just create a temporary AC file prior to publishing a DWG, and then discard afterwards. But this definitely seems like a bug that should be addressed.
