You probably created this repository from bzr-svn. bzr-svn uses a
supported-but-not-advertised format for the repository data, which is a
one-way conversion - this error indicates it is trying to down-grade
from that.

bzr upgrade --dirstate-with-subtrees

will do what you want if I recall correctly.
