No argument is allowed

When doing a "git clone 
ssh://platforms.companyname.com:40511/Support/Support/foobar.git", I get "fatal: 
No argument is allowed: /Support/Support/foobar.git".

The server is using JGit (0.8.4, with apache-sshd 0.3.0), but that error message 
isn't in the jgit source. I don't know where it originates from.

SSHing to that server gives "shell request failed on channel 0"

Someone in freenode/#git recommended I post here, although it may turn out the 
JGit mailing list is more appropriate.

Does anyone have any suggestions on how to resolve this or additional 
information?

Thanks
