Assertion Failed when importing svn into Git

Hi,

I'm trying to import my SVN repository into GIT and its throwing an Assertion Failed error message in text_delta.c Can someone help me?

The assertion failed error occurs when running 'svn diff -r 288:289' which contains only one change - a change made to a binary file. That binary file is the Eclipse dataModel file, both revs (288, 289) have the file marked as application/octet-stream using the svn:mime-type property

subversion - 1.5.4 git - 1.6.0.6

The SVN repository was started using 1.4.6, if that matters

Here's the exact error message:

------- $ svn diff -r 288:289 svn: subversion/libsvn_delta/text_delta.c:609: apply_window: Assertion `window->sview_len == 0 || (window->sview_offset >= ab->sbuf_offset && (window->sview_offset + window->sview_len >= ab->sbuf_offset + ab->sbuf_len))' failed. Aborted -------

Thanks!
