unexpected busy flag declared

Dear ROOTers,

I encountered an unexpected busy flag message while running a simple public TSelector class in a TChain.
Follows here the complete output, together with the ROOT version, of the code.
Please, find in:

   ~govoni/public/4Root

  the working example that generated this error. I run it via:

   root guardo.C

The ROOT is the 4.00/06 version, the platform is a macosx tiger one. Does anybody have a suggestion on how to face the problem? Thank you very much in advance!

Pietro
