OK,

  This looks like it is an upstream bug, Plasma is now failing to include the
username in opening the connection:

Forcing a username with sftp://david@nirvana/home/david will connect, but if
the host is in your QuickList, an additional '/' is appended, e.g.

Jun 15 22:02:56 seidr kdeinit5[4000]: log_kio_sftp:
QUrl("file:///tmp/kwrite.wWnYUs")  ->
QUrl("sftp://nirvana//stylish_policy.txt")  , permissions =  "-1" , overwrite
=  QFlags(0x4) , resume =  QFlags()
Jun 15 22:02:56 seidr kdeinit5[4000]: log_kio_sftp: "/tmp/kwrite.wWnYUs" ->
QUrl("sftp://nirvana//stylish_policy.txt") , permissions= -1 , flags QFlags(0x4)
Jun 15 22:02:56 seidr kdeinit5[4000]: log_kio_sftp:
QUrl("sftp://nirvana//stylish_policy.txt") , permissions = -1 , overwrite =
QFlags(0x4) , resume = QFlags()

However, including the username to a host not in the QuickList will complete
successfully, but with a number of ratty errors, e.g. (to a new host "2pi")
