Import of Publisher documents fails in this release on OS X. Imported immediately in 4.2.6 but in this release was a much longer delay to complete import and when the Draw doc opened it over a thousand pages of same garbage repeated on each page I looked at before quitting the app. This import worked ok on my Win 7 system with 4.3.
If you can send us the document, we can look into what may be causing the issue.
