Bug 173763

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051118 Fedora/1.5-0.5.0.rc3 Firefox/1.5

Description of problem:
/bin/su doesn't work from gnome-terminal (or xterm, for that matter). Works okay from a virtual console.

No messages are reported, but strace reveals:

read(3, "#%PAM-1.0\nauth     required     "..., 4096) = 154
read(3, "", 4096)                       = 0
close(3)                                = 0

close(1)                                = 0
munmap(0xab1000, 9680)                  = 0
exit_group(1)                           = ?
Process 16114 detached

The 'standard in must be a tty' being the line that gives it away.
