Bug#952636: grdesktop: calls rdesktop with wrong -k option if no kbd layout is selected

[Frank Doepper <fd@taz.de>]

Package: grdesktop
Version: 0.23+d040330-3.1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?
using grdesktop to connect to another host on Debian Buster
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
grdesktop
enter a Computer hostname
click Execute
   * What was the outcome of this action?
A warning message with the usage of rdesktop
   * What outcome did you expect instead?
open a rdesktop session to the named host

Apparently rdesktop is called with option "-k" without required argument
if no keyboard layout is selected explicitely.

Maybe both grdesktop and rdesktop should be removed from Debian in favor
of xfreerdp and another GUI.
