Bug#977853: proftpd-core: Fails to set up

[Hilmar Preusse]

Package: proftpd-core
Version: 1.3.7a+dfsg-4
Severity: important

Dear Maintainer,

I upgraded from -3 to -4 and now the postinst script fails to run:

Setting up proftpd-core (1.3.7a+dfsg-4) ...
usage: sftp [-46AaCfNpqrv] [-B buffer_size] [-b batchfile] [-c cipher]
          [-D sftp_server_path] [-F ssh_config] [-i identity_file]
          [-J destination] [-l limit] [-o ssh_option] [-P port]
          [-R num_requests] [-S program] [-s subsystem | sftp_server]
          destination
dpkg: error processing package proftpd-core (--configure):
 installed proftpd-core package post-installation script subprocess returned error exit status 1
Setting up fonts-lato (2.0-2.1) ...
dpkg: dependency problems prevent configuration of proftpd-dev:
 proftpd-dev depends on proftpd-core (= 1.3.7a+dfsg-4); however:
  Package proftpd-core is not configured yet.

Not sure, why there is a call to sftp client in the postins script.
