broken revlog and orphan revlog in Mercurial - How to repair?

This is what i get when i do hg verify :

repository uses revlog format 1
checking changesets
checking manifests
crosschecking files in changesets and manifests
checking files
 includes/base/class/ViewInstanceAdapter.class.php@7: broken revlog! (index data/includes/base/class/ViewInstanceAdapter.class.php.i is corrupted)
warning: orphan revlog 'data/includes/base/class/ViewInstanceAdapter.class.php.i'
158 files, 61 changesets, 270 total revisions
1 warnings encountered!
1 integrity errors encountered!
(first damaged changeset appears to be 7)

I do not use Mercurial for a long time and i don't understand what this means.

(I'm on windows using TortoiseHg, and the project is local only)
