Summary:
In a git-version-controlled environment, when you move folders via "git mv", the Xcode comparison view stops working: Although you still see the previous commits, when selecting it you get the error "The source control operation failed because no repository could be found. Make sure a valid repository exists at the specified location and try again."

In the console, you can see the following error:

"11.04.16 10:17:33,859 Xcode[41176]: #DVTSourceControl Error: -200 The source control operation failed because no repository could be found.
Underlying Error: the path 'source' does not exist in the given tree (-3)
Method: __101-[DVTSourceControlManager exportFile:inWorkingCopy:fromRevisionLocation:toDirectory:completionBlock:]_block_invoke_2"

Other SCM software like "Tower" can handle that change.

Tested with installed git 2.8.1

Steps to Reproduce:
1. Create a new Xcode project and enable git version control
2. Commit the initial state
3. Move the folder with your source-files to a different location via "git mv"
4. Commit that state
5. Reopen the project, and relocate the sources-folder
6. Open the comparison editor for a source code file

Expected Results:
I can see the version of the file before I renamed the sources-folder

Actual Results:
I get the error message "The source control operation failed because no repository could be found. Make sure a valid repository exists at the specified location and try again."

In the console I see 
"11.04.16 10:17:33,859 Xcode[41176]: #DVTSourceControl Error: -200 The source control operation failed because no repository could be found.
Underlying Error: the path '<new sources folder name>' does not exist in the given tree (-3)
Method: __101-[DVTSourceControlManager exportFile:inWorkingCopy:fromRevisionLocation:toDirectory:completionBlock:]_block_invoke_2"
