About dialog cannot be loaded once closed

[Umang Varma]

When the about page is opened from the Help menu (which is the only way to open it), and then closed, it cannot be opened again. In the second attempt, a small "window" opens which is very irritating. It does not close easily (Esc does the trick, otherwise, you have to right-click and then click close on the title bar.)

The following error appears in the terminal on second attempt:

/home/umang/Python/pynagram/Pynagram/gui/gui.py:76: GtkWarning: gtk_widget_show: assertion `GTK_IS_WIDGET (widget)' failed
  self.widgets["about_pynagram"].run()
/home/umang/Python/pynagram/Pynagram/gui/gui.py:76: GtkWarning: gtk_widget_hide: assertion `GTK_IS_WIDGET (widget)' failed
  self.widgets["about_pynagram"].run()
/home/umang/Python/pynagram/Pynagram/gui/gui.py:76: GtkWarning: gtk_label_set_text: assertion `GTK_IS_LABEL (label)' failed
  self.widgets["about_pynagram"].run()

I am unsure of whether this is a problem on our end or is upstream.

This problem is as of revno. 4.

Thanks to "days_of_ruin" for pointing out the solution! (http://ubuntuforums.org/showpost.php?p=7726400&postcount=2)

This bug has now been fixed. The solution:
Don't connect a "response" event and hide not destroy the dialogue. This results in the dialogue working, without interfering with the Close button's behavior.
