git svn woes

For some reason, I'm getting this error when trying to git svn rebase 
things from an svn repository to a git repository:

   error: patch failed: myfile:1
   error: myfile: patch does not apply

I have a simple bash script (and transcript of its output) demonstrating 
exactly what I mean:

Any hints?  Thanks in advance!
