Hi Kevin,
yes there is, sorry did not see that earlier:

> NullPointerException at CollectionRecentSubmissions
> ---------------------------------------------------

> Key: DS-1496
> URL: https://jira.duraspace.org/browse/DS-1496
> Project: DSpace
> Issue Type: Bug
> Affects Versions: 3.0
> Reporter: Joachim Bingel
> Attachments: cocoon.log.2013-02-26
>
>
> At irregular intervals, CollectionRecentSubmissions throws a
> NullPointerException. The issue can be resolved by restarting Tomcat, but of
> course this is impractical (once the problem appears it continues to do so
> until Tomcat is restarted).
> See also the discussion at [dspace-tech]:
> http://www.mail-archive.com/[email protected]/msg20749.html
> Attached is the cocoon logfile snippet with the stacktrace.
> The problem does not appear for empty collections and seems to be unrelated
> to whether Discovery is enabled or what the recent.submissions.count is set
> to in dspace.cfg.
