I tracked down the problem to the "(dp = readdir(dirp)) != NULL)"
command in process_readdir of sftp-server.c. The readdir function seems
to crash when it's called the second time. The main difference between
the first time it's called and the second is the value of
dirp->__d_dirent.__d_position. At the first time it's zero. The second
time nonzero (actually the last position of the directory). I set it to
zero, to see what happens and readdir is working correctly (lists the
directory again).

Hope, this helps a bit.
