Invoking KOReader's Dropbear SSH server from NickelMenu

Here's something weird:


If I run the Dropbear SSH server from inside KOReader, then exit KOReader, I can connect with an SSH client by password authorization (whether the client is laptop or phone).

But if I run the exact same command to invoke Dropbear as KOReader uses, except from NickelMenu, then I can't connect.

This is my NickelMenu entry for Dropbear, copied from the Telnet entry except using the Dropbear command used by KOReader (according to ps ax):
