I can't find any other Jira's about this issue and I didn't want to make a new one if there's an existing one.  We're running 2.6.2 with patches applied.  Our kernel is 1.0.13 with a few customizations.  The problem seems to stem from when the login helper tries to get the current session and returns null.  If the user is already logged in and tries to view the shared portfolio, we get a different NPE.  In both cases, the user is trying to view the portfolio by clicking on a link that was in an email that was sent to them.  Here is what the url looks like:
