Bug#831600: ksshaskpass: After upgrade from 5.6.5 to 5.7.0 it stopped working

[Diederik de Haas <didi.debian@cknow.org>]

Package: ksshaskpass
Version: 4:5.7.0-1
Severity: grave
Justification: renders package unusable

Today I made a new attempt at upgrading ksshaskpass to 5.7.0 after the
previous try failed and it failed again.
After logging in I (pretty much) always start ksshaskpass through krunner 
and that makes it so that I can ssh into several machines using keys. 
After the upgrade to 5.7 it doesn't appear in krunner anymore.

Starting it from Konsole gave a somewhat unsettling result as it dumped
the password in plaintext to stdout ... and when trying to ssh into 
another machine it still asked for my key password.
$ ksshaskpass &
[1] 3863
$ Pass a valid window to KWallet::Wallet::openWallet().
<my-password-in-plaintext>
[1]+  Done                    ksshaskpass

One thing I noticed when inspecting the debs from 5.6.5 and 5.7.0 was
that the /usr/share/application/org.kde.ksshaskpass.desktop file was
present in 5.6.5 but not in 5.7.0. 
I guess that that explains the disappearance from krunner.

When I run 'ssh-add' from Konsole thing seem to work just fine. I think
it's getting the password from kwallet (as before) and when I ssh into
another machine I'm not asked (again) for the password of my key.

If you need more info, let me know.

Cheers,
  Diederik
