I think I can reproduce similiar thing, I've tried to import project from launchpad, using eclipse plugin, hovewer it was failing with unexpected error, I've checked and same happens when using bzr from command line. When running command below on ntfs system it is failing, when run it on ext4 filesystem, everything was fine: When running: bzr branch lp:civ4stratoverlay civ.white after entering passwd for RSA key I'm receiving such error: bzr: ERROR: [Errno 1] Operacja niedozwolona: '/media/win/workspace/civ3/civ.white/.bzr/checkout/limbo/new-2/Config/init.xml' Where "Operacja niedozwolona" means - illegal operation.
