Bug Description

- in folder1, bzr init

- add somes files in folder2, commit and push in folder1

If I create a new branch, ok, the files is present.

I import a svn repository (bzr svn-import) in folder2 with success. BUT the original files are disappeared...

In folder3, bzr branch /folder1=> ok
In folder3, bzr merge /folder2 => ERROR
    bzr: ERROR: zlib.error: Error -3 while decompressing: incorrect data check
