Package: openssh-server
Version: 1:4.2p1-7
Severity: grave
Justification: renders package unusable
When I start the SSH service, it boots fine and doesn't say anything strange. However, when I connect to it, the child process serving the connection crashes pre-banner (just after the connection is established, before the SSH server says anything).
If I run it in debug mode, it says:
debug2: fd 3 setting O_NONBLOCK
debug3: privsep user:group 101:65534
debug1: permanently_set_uid: 101/65534

That was it, my bad, excuse me very much for filing a new bug report.
