Not only they overlap but they're empty.
Would 2144619 happen to be at/near the end of the RMAIL buffer (or at/near
the last position of the buffer every displayed)?

Maybe we just need to make goto-address mark its overlay with the
`evaporate' propert so they disappear as soon as they beomce empty.

I doubt it's going to be sufficient, bu it may be a good start.
