missing chk node(s) for id_to_entry maps

Hi,
I am currently unable to bzr branch lp:gcc-linaro/4.8 (in a shared repo).

This bzr repo has been created from the official FSF SVN GCC repo, but I don't know how exactly, that's why I created a new bug report since I am not sure it's related to bzr-svn.

After several minutes, I get this error:

bzr: ERROR: bzrlib.errors.BzrCheckError: Internal check failed: Cannot add revision(s) to repository: missing chk node(s) for id_to_entry maps
