I don't use ssh, but I use the git:// protocol and have also had push 
errors locally.  I run RHEL and when I get errors with git protocol I 
check /var/log/messages.  Find out where your log messages are going and 
check them.  You could also check permissions on the destination repo. 
Look at its object store recursively, ie. .git/objects/, and do "ls -la" 
to see the permissions.  People could be pushing stuff up with the wrong 
permissions and then someone else can't get to it.  Just some ideas...

v/r,
