Fatfreecrm Fat Free CRM → 0.9.10 "Alekhine"

On a standard ffcrm with demo fixtures loaded, I had the following error when trying to view the campaign dashboard.

ActionView::TemplateError (Object must be a Date, DateTime or Time object. nil given.) on line #14 of app/views/emails/_email.html.haml:
11:       = "To " << link_to(email.user.full_name, user_path(email.user))
12:       = "from " << link_to_email(email.sent_from) << ", sent on "
13:       = l(email.sent_at, :format => :mmddhhss)
14:       = " | " + link_to_function(email.collapsed? ? t(:more) : t(:less), "crm.flip_note_or_email(this, '#{t(:more)}', '#{t(:less)}')", :class => "toggle")
15: 
16:     %dt{ hidden_if(email.expanded?), :id => dom_id(email, :truncated) }
17:       %p

This was caused by an email having a nil sent_at date.

Turns out that when the email fixtures are generated, they may sometimes reference a campaign that doesn't exist - it picks a random number rand(100) to assign to the mediator_id but there are only 84 campaigns. This in turn, prevents the rake task from setting the correct dates as it doesn't find these emails.

Two solutions I could think of:

1. Increase number of demo campaigns to over 100, or
   
2. Reduce rand(100) to rand(80)

I chose method 2 and patched it here:

Hope that makes sense. and thanks for a great product.
