Python Bindings IndexError

[superm1@…]

This was submitted to the mythbuntu bug tracker at ​https://bugs.launchpad.net/mythbuntu/+bug/1051872. This should be a very recent build (9/17, git snapshot 0a56d7f) Details below:

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 *

    if dt < self._transitions[index].local[0:5]:

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

Could I get a copy of whatever zoneinfo file was installed to /etc/localtime?
