Did this problem manifest after an upgrade of perl-modules or git-svn
(you don't mention which version of git-svn you're using)?

I can't reproduce this using a simple Memoize test program run before
and after an upgrade between 5.10.1-17 and 5.10.1-18, nor using
git-svn on a simple repo (but that's because the memoized code path
isn't used there).

Can you come up with a simple recipe to reproduce this using publically
available repositories?

There's a thread about the same error message at
<http://groups.google.com/group/git-version-control/browse_thread/thread/2960fe2d4c8c61b0?pli=1>
which is unfortunately not very conclusive. Does reverting to an old
version of git-svn help at all?

Thanks,
Dominic.
