+### Please describe the problem.
+
+On Windows, a 10GB file of mine is successfully indexed (``git annex add``'ed), but ``git annex sync --content`` always fails with rsync, saying "recvkey: received key with wrong size". This is the largest file I've tested so far, and the only one that's failed.
+
+### What steps will reproduce the problem?
+
+1. Copy a 10GB file to a working copy (mine is ''PNG_Sequence.rar'', 10 361 629 980 bytes).
+2. Run ``git annex add``
+3. Run ``git annex sync --content``
+
+### What version of git-annex are you using? On what operating system?
+
+Windows 7 x64 with:
+
+    git-annex version: 5.20141128-g70f997e
+    build flags: Assistant Webapp Webapp-secure Pairing Testsuite S3 WebDAV DNS Feed
