git svn problem

Hello, I have a problem with git.

Basically, here is what I have. I access a svn repository through git.
Until now, on python files, everything worked fine.

But lately I also added some pyd, dll and lib files on the repository. THe
first update went well. But then, these files have been modified and since
then I can't update. These files were added from a windows computer with
TortoiseSvn on the svn repository.

If I do a git svn rebase on linux, everything works fine.

If I do a git svn rebase on windows with msysgit (and also tortoisegit), I
have the following error : fatal: write error: Invalid argument

If I do a git svn rebase on windows with cygwin, I have the following
error : didn't find newline after blob at
/usr/lib/perl5/vendor_perl/5.10/Git.pm line 916

I tried several stuff (autocrlf true/false, safecrlf true/false), adding
.gitattributes file with the following line *.* -crlf -diff -merge and
nothing worked.

I'm a little stuck here so any suggestion would be welcome.

Thanks in advance.
