 Sugar never calls gtk.gdk.threads_init(), so any attempt to use threads in
 code called by the sugar shell (control panel code in particular) causes
 sugar to crash -- python throws an assertion about its GILlock.

 The fix is very simple: in /usr/share/sugar/shell/main.py, right after:
 {{{
 pygtk.require('2.0')
 import gtk
 import gobject
 }}}
 add the line:
 {{{
 gtk.gdk.threads_init()
 }}}

 Voila! No more crashes.

 Found this bug while writing the 'activity update' sugar control panel,
 which uses threads to keep the UI responsive while it is
 doing network operations in the background to update activity
 version status.
