#9864: [a11y] Attempting to get default text attributes crashes Pidgin Gtk
------------------------+---------------------------------------------------
Reporter:  JoanieDiggs  |        Type:  defect       
  Status:  new          |   Component:  pidgin (gtk) 
 Version:  2.5.8        |    Keywords:  accessibility
------------------------+---------------------------------------------------
 Steps to reproduce:

 1. Launch Pidgin and Accerciser (http://live.gnome.org/Accerciser)

 2. In Pidgin open a chat window

 3. In Accerciser, select the accessible associated with the editable text
 object at the bottom of the window.*

 4. In Accerciser, switch to the Interface Viewer, expand Text (Editable),
 and check the 'Include defaults' checkbox.*

 * I'll attach a screenshot in case you're not familiar with Accerciser.

 Expected results: Pidgin would not crash.

 Actual results: Pidgin crashes 100% of the time.
