cannot join more than two projects after importing from git

[Francesco Chiechi]

this is a riedition fo Bug #370710:

if I import three or more projects from git an then try to join them, I succeed in joining the first two, but I get
"ERROR: File id {TREE_ROOT} already exists" when importing the third

I searched in the code but I don't have enough knowledge to find and propose a solution

I think it has something to do with these lines in bzrlib/inventory.py:

# This should really be an id randomly assigned when the tree is
# created, but it's not for now.
ROOT_ID = "TREE_ROOT"

or maybe in the way Inventory is initialized in pre_process_files() in plugins/fastimport/bzr_commit_handler.py

thankyou for your work

Sorry for the duplication (I didn't find it searching).

Anyway I don't understand if there is a solution for this problem (I mean joining projects imported from git)

thankyou again
