[Mono-aspnet-list] Expired cookie causes NullReferenceException - Mono / MVC5 ASP.Net

[Will Tyler]

Hi,
I'm new to the group and looking for some insight on a problem that I can't
seem to figure out.  I have an ASP.Net MVC5 application running on Ubuntu
using Mono, Apache, and PostgreSQL.  When the authentication cookie expires
(such as when I re-visit the app 30 minutes later), I get a
System.NullReferenceException.

I'm just using simple forms based authentication.  No external providers,
nothing Windows specific (that I'm aware of), no two-factor authentication,
etc.  I'm at a loss here.  The only way to regain access to the site is to
delete cookies, open in another browser or incognito window, or restart
apache.

Has anyone run into this problem before?

Thanks in advance for any input.
