Comment 2 for bug 316891

I wonder if it should be an error at all. Post-commit hooks can fail but svn ignores the status of them (unlike a pre-commit hook); the commit has already succeeded. When you commit with svn it will just give you a warning with the error output of the post-commit hook.

So if that warning is indeed the cause it should really only be a warning on the bzr side as the push has succeeded.
