scp 2.9.9p2 doesn't work

[Lars Hecking]

 I just upgraded openssh on my Solaris 8 boxes from 2.9p2 to 2.9.9p2,
 and scp has stopped working. Remote logins with ssh do work, though.
 Both client and server run 2.9.9p2.

 Please let me know if you need more information (configure options,
 config files etc.). I'm not on the list, so CC's would be appreciated.
 Thanks!
