JS>> Most likely, your sed has problems with a sed script in function
JS>> get_author_ident_from_commit. I tested it like this:

JS>> $ sh -c '. $(git --exec-path)/git-sh-setup;
JS>>                 get_author_ident_from_commit HEAD'
JS>> GIT_AUTHOR_NAME='Johannes Sixt'
JS>> GIT_AUTHOR_EMAIL='j6t@kdbg.org'
JS>> GIT_AUTHOR_DATE='@1350025129 +0200'

JS>> -- Hannes

IB> Both systems have GNU sed 4.2.1 installed. I wrote a wrapper script wor sed.
IB> It's output attached.
IB> The difference is letter case in sed input data:
IB> Solaris:
IB>   /^AUTHOR /
IB> Windows:
IB>   /^author /

The culprit is bad $PATH :
When git-filter-branch runs, for some reason two new entries precede
/usr/bin in it:
     /tmp/777/.ilya-sparc/bin
     /home/tester/.ilya/opt/SNiFF-3.2.1/bin
     /export/home/testora/app/testora/product/11.2.0/client_32/bin
    +/usr/xpg6/bin
    +/usr/xpg4/bin
     /usr/bin
     /home/tester/apache-ant-1.7.1/bin
     /usr/jdk/instances/jdk1.5.0//bin

And /usr/xpg6/bin/tr fails to make "AUTHOR" lowercase.
