log cache issues

Stefan^2,

You've been very quiet lately on the list. There are some issues with
the log cache which need someone working on them. If you don't want to
do it anymore, that's fine, but a little notice would be nice.

If you still have the time to look after some issues, here's one for
you: the attached script shows a problem with the log cache. The blame
at the end of the script crashes because the cache fails to add some
logs when handling the renames.

I've also attached a patch which would fix this issue, but I don't have
a good feeling about the patch: the cache is your code so you're more
familiar with it than I am.

Stefan
