I've seen similar things with auto routed tracks. Sometimes, if I zoom
right in and play about with layer visibility a bit I can see a very
small piece of track under/over a via. Deleting this makes the drc error
go away. I assume these bits of track are some kind of artifacts of the
auto route process. I don't know why this should produce that particular
error.
