I'm getting the same thing on bzr 0.90 on gutsy. Most operations fail with memory error, bzr check fails with 'Unprintable exception BzrCheckError...'. Tried creating another branch from the original one, but it too fails, this time with 'InstallFailed: Could not install revisions...'. This may be a damaged branch but I really don't know how it could have happened. I'm attaching a part of ~/.bzr.log and the dirstate file.
