+### Please describe the problem.
+I have a V6 annex in adjusted branch with a submodule, which also is a V6 annex in adjusted branch.
+There staged changes in the superproject, while the submodule is clean. Calling git-annex-sync in the superproject now leads to:
+
+[[!format sh """
+% git annex sync
+commit  (recording state in git...)
+
+[adjusted/master(unlocked) 3c8d350] git-annex in me@mycomputer:/tmp/datalad_temp_test_AnnexRepo_statusGmqM5E
+ 4 files changed, 4 insertions(+), 2 deletions(-)
+ create mode 100644 fifth
+ create mode 100644 sub/third
+ok
+fatal: entry 'submod' object type (blob) doesn't match mode type (commit)

+git-annex: user error (git ["--git-dir=.git","--work-tree=.","--literal-pathspecs","mktree","--batch","-z"] exited 128)

+
+### What steps will reproduce the problem?
+
+Sadly I wasn't able to reproduce it outside the datalad test it is happening in.
+I will provide the steps to achieve that situation, whenever I figured them out.
+But may be just the error message is sufficient to address the problem ...
