[pygtk] Core dump from libglade

[Paul Clifford]

This may actually be a bug in libglade itself rather than the Python
bindings, but it's simpler to demonstrate it in Python.  Essentially, if
you try to use get_widget (or get_widget_by_longname) for a combo box's
entry widget you'll get a core dump.

Here's some Python code and a trimmed down glade file to demonstrate:


(test.py)

from gtk import *
import libglade

widgets = libglade.GladeXML('libglade_bug.glade')
window1 = widgets.get_widget('combo-entry1')
mainloop()


(libglade_bug.glade)

      <text_max_length>0</text_max_length>
      <text></text>
    </widget>
  </widget>
</widget>
