Unable to define Starter device: ENOENT (9.4.2)

After altering the property_device_hist, as described in cppTango#1142 (moved), I am getting the error below when trying to define a Starter device using tango_admin, as documented in starter.html:

host=$(hostname -s)
tango_admin --add-server Starter/$host Starter tango/admin/$host
/usr/lib/tango/Starter $host

ENOENT
2  No such file or directory
Tango exception
Severity = ERROR
Error reason = API_BadConfigurationProperty
Desc : System property polled_attr for device tango/admin/autopkgtest-lxc-tlhafa has wrong syntax
Origin : void Tango::Util::polling_configure() at (./lib/cpp/cppapi/server/utils_polling.cpp:121)

Received a CORBA_Exception
Exiting
terminate called after throwing an instance of 'CORBA::OBJECT_NOT_EXIST'
Aborted

I am unable to say yet if this is a code, documentation or user bug.

Any thoughts?
