What steps will reproduce the problem?

1. I upgraded the Tortoize git version from 1.8.11 to 1.8.13
2. Opened the Diff with previous version window
3. I select log option from version 1 drop down
4. It displays the "Could not open log. libgit reports: bad object 0000000000" error message

What is the expected output? What do you see instead?
Expected output: Display all the logs
Actual output: "Could not open log. libgit reports: bad object 0000000000" error message
