[Haskell-cafe] Index for local documentation is incomplete

[Francesco Ariis]

Dear Haskellers,
    I have a problem with local haddock documentation. Specifically, the
documentation gets built but the index.html is not updated. As an example,
here is the bottom part of the log of a package I installed a few days ago:

> Haddock coverage:
>  100% (  6 /  6) in 'System.FilePath.Manip'
>  100% (  7 /  7) in 'System.FilePath.GlobPattern'
>  100% (  2 /  2) in 'System.FilePath.Glob'
>   65% ( 41 / 63) in 'System.FilePath.Find'
> Documentation created: dist/doc/html/filemanip/index.html
> Creating package registration file: /tmp/pkgConf-filemanip-0.3.66815.3
> Installing library in
> /home/user/.cabal/lib/i386-linux-ghc-7.8.3/filemanip-0.3.6.3
> Registering filemanip-0.3.6.3...

The documentation files are present in
~/.cabal/share/doc/i386-linux-ghc-7.8.3/filemanip-0.3.6.3/html/index.html

but when if I open `~/.cabal/share/doc/index.html`, there is no
`System.FilePath.Find` module.

cabal version is 1.22.0.0, GHC 7.8.3

Any idea on how to diagnose this?
