IndexOutOfBoundsException displaying Pie Chart

When requesting a Pie Char for some Statistics I get an IndexOutOfBoundsException. It seems to be with the custom fields Burger options, Issue Key Searcher, Reason For Rejection, Test Select.

You can reproduce this at jira.atlassian.com for the JIRA project.

Here is the full error:
