Hi,

Finished a big re-shuffle of a big project, while other developers continued. Worked really well. Thanks guys! But now I have two top directories and I want to create two new repositories, each containing one of these directories (because the one holds copyrighted data and we want the other to become public software). So, I happily run

	$ git filter-branch --subdirectory-filter RDF HEAD

Where RDF is an existing directory.  I get:

Rewrite 95807fe01c39d3092e3ac3a98061711323154d77 (1/12)fatal: Not a valid object name 95807fe01c39d3092e3ac3a98061711323154d77:RDF Could not initialize the index

I tried the procedure on some smaller test projects and it all worked just fine. Running git version 1.5.3.4 on SuSE Linux. Also ran "git fsck --full", which completed without any message.

Git show says:

    Merge branch 'master' of /home/eculture/eculture

Any clue?

	Thanks --- Jan
