Vi riporto una comunicazione di Minisini posta all'interno di una discussione:
" In revision #6842, the GB_X11_INIT_THREADS environment variable can be
defined to "1" to enable thread initialization in gui components.
I can't do more, because this initialization must be done before calling
any toolkit function. So you will have to define this variable by hand when needed.
This can be done in the Main() function of your startup class, provided
that you do no GUI thing at all before.
Regards,
