Title:
  mythtv python bindings crash with an IndexError

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Fix Committed
Status in MythTV:
  Fix Released

Bug description:
  Hi,

  I'm using the latest 0.26 precise mythtv APKs. the current libmythtv-
  perl (all the other mythtv packages are the same version) version is

  2:0.26.0~master.20120917.0a56d7f-0ubuntu0mythbuntu2

  For the last week or so, I've realized that I cannot download
  metadata. I debugged further and the mythtv python libraries are
  throwing an IndexError. The full error is

  root@mythtv:~/Data# mythwikiscripts
  Traceback (most recent call last):
    File "/usr/bin/mythwikiscripts", line 3, in <module>
      from MythTV.wikiscripts import *
    File "/usr/lib/python2.7/dist-packages/MythTV/__init__.py", line 41, in <module>
      from dataheap import *
    File "/usr/lib/python2.7/dist-packages/MythTV/dataheap.py", line 583, in <module>
      class Job( DBDataWrite, JOBTYPE, JOBCMD, JOBFLAG, JOBSTATUS ):
    File "/usr/lib/python2.7/dist-packages/MythTV/dataheap.py", line 589, in Job
      _defaults = {'id':None,     'inserttime':datetime.now(),
    File "/usr/lib/python2.7/dist-packages/MythTV/utility/dt.py", line 237, in now
      obj = super(datetime, cls).now(tz)
    File "/usr/lib/python2.7/dist-packages/MythTV/utility/dt.py", line 55, in utcoffset
      return timedelta(0, self._get_transition(dt).offset)
    File "/usr/lib/python2.7/dist-packages/MythTV/utility/dt.py", line 38, in _get_transition
      if dt < self._transitions[index].local[0:5]:
  IndexError: tuple index out of range(

  I'm not sure how to fix this. I've removed all the python scripts and
  reinstalled. no change. i've diffed the python scripts (dataheap.py
  and dt.py) with the mythth git version. They are identical.

  I've added the timezone data to mysql and verified that it works by
  logging into mysql and doing something like

  SELECT CONVERT_TZ('2012-06-07 12:00:00', 'GMT', 'America/New_York');

  the correct response (shown below) is returned

  +--------------------------------------------------------------+
  | CONVERT_TZ('2012-06-07 12:00:00', 'GMT', 'America/New_York') |
  +--------------------------------------------------------------+
  | 2012-06-07 08:00:00                                          |
  +--------------------------------------------------------------+

  What can I do to fix this?

  my mythtv box is running the latest precise packages.

  It might be a mythbuntu and/or ubuntu precise issue as nobody is
  reporting this error (which affects every python script) on the mythtv
  mailing lists and bug repository.

  Thanks,

  Raj
