I can no longer git svn rebase (using msysgit on Windows 7).
The error starts with:
Byte order is not compatible at ../../lib/Storable.pm
And ends with:
Could not unmemoize function 'lookup_svn_merge', because it was not memoized to begin with
It may be overkill, but I've tried reinstalling the fule Git Extensions package with msysgit. I also made sure that cygwin git and/or perl aren't interfering. I seem to be stuck rebasing consistently on this one commit; before this, it was fine. A colleague who uses git-svn on Windows against the same subversion repository had no problems, so it's something specific to my development machine.
