Indy does use threads extensively...
Since I could not find any place to set a project wide defined symbol
UseCThreads I did this instead in the lpr file:

program WiFiConfig;

{$mode objfpc}{$H+}

  Interfaces, // this includes the LCL widgetset
  Forms, indylaz, FormMainConfig, wificommhandler
  { you can add units after this };

{$R *.res}

  RequireDerivedFormResource := True;
  Application.CreateForm(TfrmMainConfig, frmMainConfig);

After this the program does no longer crashes when I try to connect to
the device, but it does not connect either because I am having
problems making OpenVPN to the network where the device lives work
from the RPi box.
I have to solve this somehow, it works fine from my Windows7 PC so
there I can interact with the device.
Problem for another forum, though.
