multithreading: from gtk+1.2 to gtk+2.2

[Claudio Pascual <a2629 dis ulpgc es>]

Hello everybody,

    I had my gtk+1.2 app running without any problem. I used the 
gdk_threads_enter/gdk_threads_leave as described in docs and mailing 
lists messages.
    Then, a week ago I moved to gtk+2.2. Now I cannot make it run 
without seeing \'Xlib: unexpected async reply (sequence 0x28)!\' Nothing 
is shown in the window.
    Any idea? Thanx in advance,

Claudio Pascual
