[sugar] git failed

[Mikus Grinbergs]

For the fun of it, tried to 'git-clone' sugar (on my non-RedHat 
system, to directory /home/olpc).  Got the messages: "cd: 409: can't 
cd to /home/olpc/sugar/.git/refs/remotes/origin" "fatal: Not a valid 
object name HEAD".

In the same place, using the same syntax, tried to 'git-clone' an 
unrelated Linux application (from its repository).  That worked.

How can I find out why my 'git-clone sugar' is having problems?
