IndexError when cloning on Windows 10

See original GitHub issue

On Windows 10, pushing a newly created repo as per the instructions in the wiki produces no errors. However when cloning that repo back, I get the following error

A quick update: figured out the bug, it shows up on Git versions before https://github.com/git/git/commit/f06ab027efd2cff4c4319354f1ad7d5f09e853a1 (so the latest release that works fine in this situation is v2.22.0). It has to do with the empty tree being in the commit history, so it should be pretty rare. There is also no data loss as a result of this, just a crash when cloning.

As a workaround, you can upgrade your installed git, and it should start working again. I should have a patch for this soon once I figure out the cleanest way to do it.

I am on Ubuntu 19.10, with Python 3.7.5 and git-remote-dropbox 1.1.2 installed through pip.

The repo I am having a problem with is my home page, and is about 180MB of data. While there is nothing too secret about it, I’d feel better sharing it through a private message, if thats ok.

Edit: I’ve just shared the problematic dropbox folder with you on your @mit.edu address.
