A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.
/var/www/cgi-bin/pl.cgi in ()
373 url = publication[PUB_IMAGE]
374 spliturl_at_dots = url.split('.')
375 second_url_part = spliturl_at_dots[1]
376 third_url_part = spliturl_at_dots[2]
377 print '<table>'
second_url_part undefined, spliturl_at_dots = ['url']

<type 'exceptions.IndexError'>: list index out of range
