 Can you post a GDB stack trace?  You should be able to obtain this by
 attaching gdb to the scp child process (with gdb /usr/bin/scp PID)
 while ssh prompts for the password.

Or even telling strace to follow child processes (since it's the
underlying ssh process that's segfaulting, not scp itself) as well as
turning on scp's own debugging might help:

  strace -f scp -vvv -r [EMAIL PROTECTED]:/sbin .

Thanks,

while ssh prompts for the password.

Can you reproduce this with Debian's dropbear?
