[orca-list] strange error

[Christopher Moore <chris w1gm gmail com>]

Hello,
I couldn't capture the entire traceback, but maybe there's enough to 
look at.  
At the bottom we seem "global name exwrap" not defined.  I'm running 
3.0.1 and received this when going into thunderbird.

  File "/usr/lib/python2.7/site-packages/orca/script.py", line 406, in 
processOb
jectEvent
    self.listeners[key](event)
  File 
"/usr/lib/python2.7/site-packages/orca/scripts/toolkits/Gecko/script.py",
 line 1486, in onChildrenChanged
    self.liveMngr.handleEvent(event)
  File "/usr/lib/python2.7/site-packages/orca/liveregions.py", line 165, 
in hand
leEvent
    politeness = self._getLiveType(event.source)
  File "/usr/lib/python2.7/site-packages/orca/liveregions.py", line 522, 
in _get
LiveType
    uri = self._script.bookmarks.getURIKey()
  File 
"/usr/lib/python2.7/site-packages/orca/scripts/toolkits/Gecko/bookmarks.p
y", line 289, in getURIKey
    uri = self._script.utilities.documentFrameURI()
  File 
"/usr/lib/python2.7/site-packages/orca/scripts/toolkits/Gecko/script_util
ities.py", line 209, in documentFrameURI
    attrs = documentFrame.queryDocument().getAttributes()
  File "/usr/lib/python2.7/site-packages/pyatspi/document.py", line 60, 
in getAt
tributes
    ret = exwrap(Atspi.Document.get_attributes, self.obj)
NameError: global name 'exwrap' is not defined

Perhaps this is the result of a block of code which was never 
encountered during testing.
