Git svn clone: ​​fatal: the link is in the wrong format

Question

I use git svn clone to convert svn repo to git and run into problems with this. My first issue is

fatal: Not a valid object name refs/remotes/Customer Assistance cat-file commit refs/remotes/Customer Assistance: command returned error: 128 

I tried the solution mentioned here here , but now it gives me the following error -

 fatal: Reference has invalid format: 'refs/remotes/Customer Assistance' for-each-ref --format=%(refname) refs/: command returned error: 128 

PS: I do this on a windows machine and I am using git 1.8.3.
