'task push' fails when there are recurring tasks

[campbellr]

I suspect this is related to issue #25 (supporting recurring tasks).

Environment:


Request Method: PUT
Request URL: http://taskweb.herokuapp.com/taskdb/undo.data

Django Version: 1.3
Python Version: 2.7.2
Installed Applications:
['django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.sites',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'djblets.datagrid',
 'djblets.util',
 'django.contrib.admin',
 'task']
Installed Middleware:
('django.middleware.common.CommonMiddleware',

Traceback:

  16.         if undo[1].startswith('old'):

Exception Type: IndexError at /taskdb/undo.data
Exception Value: list index out of range

and the state of the locals at the time of the exception:

segment     

'" recur:"biweekly" status:"recurring" uuid:"18927227-29a0-421e-84aa-052196a27fbb"]\n'

undo    

['" recur:"biweekly" status:"recurring" uuid:"18927227-29a0-421e-84aa-052196a27fbb"]']

line    

'" recur:"biweekly" status:"recurring" uuid:"18927227-29a0-421e-84aa-052196a27fbb"]'

So something obviously went wrong with the undo parsing
