Hmm. Each uidlist has:

1. entry with filename X
2. entry with a different filename but with GUID X (=message was copied elsewhere and back)
3. entry once again with a filename X

So .. I guess this has to do with copying the same message back and forth, possibly expunging it in the middle. I'll try to reproduce tomorrow.
