Erro htab

[sygecom]

O erro acontece quando clico em uma aba de uma tela.

Parte do código, mesmo assim vou tentar reproduzir um exemplo mais simples em um projeto aberto que tenho:
https://github.com/syggroup/xbase_scm

@ 002,140 TAB oTab ITEMS {} SIZE 1020,515;
ON GETFOCUS {|| oTab:SetFocus() };
ON INIT {|oCtrl|oCtrl:bChange:={|o,nPage|oTab:settab(nPage), oTab:ChangePage(nPage), IF(UPPER(ALLTRIM(o:aTabs[nPage]))='LOGO MARCA',CARREGA_LOGO_MARCA(cNOMEIMG),.T.)  } }

Estou tendo o erro abaixo:

Consegui reproduzir o erro colocando no A.PRG da pasta SAMPLES.

A tela abre normalmente, quando clica na segunda aba da o erro.

Colocar no MENU uma chamada:
ErrorPreview( 'AAAAAAAAAAAAAAAAAA')

STATIC FUNCTION ErrorPreview( cMess )
   LOCAL oDlg, oEdit, oTAB

   INIT DIALOG oDlg TITLE "Erro No Sistema SCM Vs. 1.0";
   ICON HIcon():AddResource(1004)  ;
