How to fix (fairly minor) error reported by verify?

[Chris Green]

How do I fix this:-

    chris$ hg verify
    checking changesets
    checking manifests
    crosschecking files in changesets and manifests
    checking files
     clearMuttHtml@?: rev 0 points to unexpected changeset 135
     (expected 134 137)
     sendCamPics at 135: 1247b8363d74 not in manifests
    427 files, 163 changesets, 530 total revisions
    1 warnings encountered!
    2 integrity errors encountered!
    (first damaged changeset appears to be 135)
    chris$ 

... or do I even need to worry about it?
