git svn show-ignore bug?

Hi there, in the IRC channel today, someone asked me to report this  
behavior to you because they suspect a bug in show-ignore.

Ok, so here's the output of git svn info:

Path: .

Repository Root: https://www.iam.unibe.ch/scg/svn_repos
Repository UUID: 54883e8d-cf1d-0410-83d6-f114b9419f37

I can do git svn rebase, git svn fetch, and those things work.  
Dcommit, works, too. But git svn show-ignore >> .gitignore does not  
work.

This is the dialog with the system:
Nikos-Mbp-3:svn_repos niko$ git svn show-ignore >> .gitignore

That's all the info I have, I'm afraid. I'm sure that the password is  
correct, as it works from XCode.

Thanks in advance, cheers,
