Oops... I missed your request, sorry. I am able to reproduce in our full tree, I will try to make a script for you. The base cause seems very clear though in the topmost trace, the bzr mv --auto **renames**: vp-soap-server/test/nl/itris/soap/server => vp-soap-server/test/nl/itris/soap/util but the source dir (vp-soap-server/test/nl/itris/soap/server) contains files and they are actually touched afterwards - this cannot be the case after the move.. I made a new testcase and tried it with bzr-1.17: jal@odeon:~/bzr/xxx$ bzr status removed: vp-soap-server/test/nl/itris/soap/server/DummySoapCallClass1.java vp-soap-server/test/nl/itris/soap/server/JaxbInputObject.java vp-soap-server/test/nl/itris/soap/server/TestAnnotatedCall.java vp-soap-server/test/nl/itris/soap/server/TestFormatDecoders.java vp-soap-server/test/nl/itris/soap/server/TestJaxb.java vp-soap-server/test/nl/itris/soap/server/TestMimeDecoders.java vp-soap-server/test/nl/itris/soap/server/TestXmlExecutor.java unknown: vp-soap-server/test/nl/itris/soap/newone/ vp-soap-server/test/nl/itris/soap/server/FormatDecodersTest.java vp-soap-server/test/nl/itris/soap/server/JaxbTest.java vp-soap-server/test/nl/itris/soap/server/SoapDummyCallClass1.java vp-soap-server/test/nl/itris/soap/server/XmlExecutorTest.java jal@odeon:~/bzr/xxx$ tar czf ~/testbzr-xxx . jal@odeon:~/bzr/xxx$ bzr mv --auto vp-soap-server/test/nl/itris/soap/server => vp-soap-server/test/nl/itris/soap/newone vp-soap-server/test/nl/itris/soap/server/DummySoapCallClass1.java => vp-soap-server/test/nl/itris/soap/server/SoapDummyCallClass1.java vp-soap-server/test/nl/itris/soap/server/TestFormatDecoders.java => vp-soap-server/test/nl/itris/soap/server/FormatDecodersTest.java vp-soap-server/test/nl/itris/soap/server/TestJaxb.java => vp-soap-server/test/nl/itris/soap/server/JaxbTest.java vp-soap-server/test/nl/itris/soap/server/TestXmlExecutor.java => vp-soap-server/test/nl/itris/soap/server/XmlExecutorTest.java jal@odeon:~/bzr/xxx$ bzr status bzr: ERROR: exceptions.AssertionError: Could not find target parent in wt: vp-soap-server/test/nl/itris/soap/server parent of: (('vp-soap-server/test/nl/itris/soap/server', 'FormatDecodersTest.java', 'testformatdecoders.j-20090811164112-c8rqxirf7yq88zvh-1190'), [('f', '', 0L, 0, 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'), ('r', 'vp-soap-server/test/nl/itris/soap/server/TestFormatDecoders.java', 0L, 0, '')]) Traceback (most recent call last): File "/usr/lib/python2.6/dist-packages/bzrlib/commands.py", line 835, in exception_to_return_code return the_callable(*args, **kwargs) File "/usr/lib/python2.6/dist-packages/bzrlib/commands.py", line 1030, in run_bzr ret = run(*run_argv) File "/usr/lib/python2.6/dist-packages/bzrlib/commands.py", line 647, in run_argv_aliases return self.run(**all_cmd_args) File "/usr/lib/python2.6/dist-packages/bzrlib/commands.py", line 1045, in ignore_pipe result = func(*args, **kwargs) File "/usr/lib/python2.6/dist-packages/bzrlib/builtins.py", line 310, in run show_pending=(not no_pending), verbose=verbose) File "/usr/lib/python2.6/dist-packages/bzrlib/status.py", line 118, in show_tree_status want_unversioned=want_unversioned) File "/usr/lib/python2.6/dist-packages/bzrlib/tree.py", line 95, in changes_from want_unversioned=want_unversioned, File "/usr/lib/python2.6/dist-packages/bzrlib/decorators.py", line 138, in read_locked result = unbound(self, *args, **kwargs) File "/usr/lib/python2.6/dist-packages/bzrlib/tree.py", line 891, in compare want_unversioned=want_unversioned) File "/usr/lib/python2.6/dist-packages/bzrlib/delta.py", line 230, in _compare_trees want_unversioned=want_unversioned): File "_dirstate_helpers_pyx.pyx", line 1350, in bzrlib._dirstate_helpers_pyx.ProcessEntryC.__next__ File "_dirstate_helpers_pyx.pyx", line 1609, in bzrlib._dirstate_helpers_pyx.ProcessEntryC._iter_next File "_dirstate_helpers_pyx.pyx", line 1211, in bzrlib._dirstate_helpers_pyx.ProcessEntryC._process_entry AssertionError: Could not find target parent in wt: vp-soap-server/test/nl/itris/soap/server parent of: (('vp-soap-server/test/nl/itris/soap/server', 'FormatDecodersTest.java', 'testformatdecoders.j-20090811164112-c8rqxirf7yq88zvh-1190'), [('f', '', 0L, 0, 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'), ('r', 'vp-soap-server/test/nl/itris/soap/server/TestFormatDecoders.java', 0L, 0, '')]) bzr 1.17 on python 2.6.2 (linux2) arguments: ['/usr/bin/bzr', 'status'] encoding: 'UTF-8', fsenc: 'UTF-8', lang: 'en_US.UTF-8' plugins: bzrtools /usr/lib/python2.6/dist-packages/bzrlib/plugins/bzrtools [1.17] commitchecker /home/jal/.bazaar/plugins/commitchecker.py [unknown] fastimport /home/jal/.bazaar/plugins/fastimport [0.9dev] launchpad /usr/lib/python2.6/dist-packages/bzrlib/plugins/launchpad [1.17] netrc_credential_store /usr/lib/python2.6/dist-packages/bzrlib/plugins/netrc_credential_store [1.17] qbzr /home/jal/.bazaar/plugins/qbzr [0.14dev] rebase /home/jal/.bazaar/plugins/rebase [0.5.4dev] repodetails /home/jal/.bazaar/plugins/repodetails [1.9dev] xmloutput /usr/lib/python2.6/dist-packages/bzrlib/plugins/xmloutput [0.8.3] *** Bazaar has encountered an internal error.
