+### Please describe the problem.
+
+git-annex failed to update the local adjusted branch after `git annex drop` stopped abruptly. In turn, `git annex drop` stopped abruptly because a `git annex copy --from X --to Y` had to be stopped (CTRL-C) because of lack of space.
+
+(Perhaps there are two issues here: `drop` being unable to cope with the unexpected situation, and the adjustment code being unable to cope with the weird stat left by `drop`'s abrupt interruption.)
+
+### What steps will reproduce the problem?
+
+```
+$ git copy -J4 --from X --to Y
+[notice that git-annex starts saying "not enough free space, need 27.87 MB more"]
+[kill process with CTRL-C]
+$ git annex drop dirF/
+drop dirF/a/a1.txt ok
+drop dirF/a/a2.txt ok
+[...]
+error: Your local changes to the following files would be overwritten by checkout:
+       dirF/a/a1.txt
+       dirF/a/a2.txt

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+git-annex is too good. It so rarely causes problems that one does not develop the "git-annex troubleshooting muscle". :)
