When using Special:Import to do a transwiki import (e.g., from <https://meta.wikimedia.org/wiki/Special:Import>), if the destination title already exists, the revisions will just be "merged" (dumped) onto the same title, without warning the user. This is pretty awful. I couldn't find a bug that was tracking this issue. Somewhat related to bug 6808.
