Git re-creates newly added directory when it is pushed

I create a new directory, add it to git and push it.

After push it says: Unable to read current working directory: No such 
file or directory

Why does Git have to delete and then create again the directory when it 
is already there?


This isn't a big issue, but it is very odd that git deletes the working 
directory.
