Patch fixes the problem. A extra g_object_ref() was added, same as GtkWindow code (666 bytes, patch)

Description Arjan J. Molenaar 2002-09-10 12:47:09 UTC 
The gnome.ui.About class causes a core dump. The following code doesn''t work:

from gnome.ui import About
import gtk

def end(win):
    gtk.main_quit()

def func():
    about = About(name='test', version='1', copyright='GPL', comments='',
                  authors=('arjan',))
    about.connect("destroy", end)
    about.show()
    #win = gtk.Window()
    #win.connect("destroy", end)
    #win.show()

func()
gtk.main()

When commenting 'about' and uncommenting the 'win' code it works as expected.

Comment 2 James Henstridge 2002-09-10 12:57:18 UTC 
It looks like you have forgotten to run gnome.init().  The call should
look something like this:
  gnome.init('program name', 'version number')

This call should be done after importing gnome.ui.  If you still have
troubles, make sure you are using libgnome-2.0.5, which fixes a bug in
gnome_program_init() that solves some initialisation issues.
Comment 3 Arjan J. Molenaar 2002-09-10 14:01:45 UTC 
So I added
import gnome
gnome.init('app', '1')

at the beginning of the file I mentioned before...
... still crashes (complaining about having no main loops to quit).

I did some checking, and also GnomeApp does an extra refcount, so does
GnomePropertyBox. But GnomeAbout doesn't increase the refcount (it's
defined in ui.override).
Comment 4 James Henstridge 2002-09-10 14:16:14 UTC 
Yeah.  I posted the response before seeing your patch.  The patch
sounds fine, and I will integrate it.
Comment 5 Arjan J. Molenaar 2002-11-03 10:33:12 UTC 
I would really like the about dialog to be fixed. It makes my app
(Gaphor) even more stable.

Thanks

Thanks for the patch.  I have applied it.
