[ROOT] Problem compiling GUI application

Dear Rooters

Enclosed is a very primitive GUI application. As long as it
includes a TRootEmbeddedCanvas class, everything is ok.
(Uncomment MyGuiA.h line 21 and MyGuiA.cxx lines 55,56,76.)

However, if I compile it without fCanvas, I am still able to
compile it, but I get the following runtime error:

[localhost:~/ROOT/rootcode/test] cc% ./MyGuiA
Warning in <TClassTable::Add>: class TGHorizontal3DLine allready in 
TClassTable
Warning in <TClassTable::Add>: class TGVertical3DLine allready in 
TClassTable
Warning in <TClassTable::Add>: class TGApplication allready in TClassTable
etc.....
etc....
Warning in <TClassTable::Add>: class TGCheckButton allready in TClassTable
Warning in <TClassTable::Add>: class TGSearchType allready in TClassTable
Warning in <TClassTable::Add>: class TGFileInfo allready in TClassTable

  *** Break *** bus error
Abort

I have the following questions:
1, Can someone explain why I cannot run my application?
2, What do these warning messages mean?
3, When does ROOT usually give these warning messages?

(I am running root 3.05/02 on MacOS X 10.1.2)

Thank you in advance for your help.

Best regards
Christian
