[Pangloss] Apache: Application Error: no view present!

[Bruno Postle]

I'm getting further with Pangloss on Apache, but with another
intermittent problem.

I've nuked the old database (there seemed to be a permanent Pixie
lock) and have Pangloss running with apache.

The front-page loads, but all of the links respond with a page with
the message: "Application Error: no view present!" - Except
_sometimes_ it's ok.

This is the log when it fails (debug level 2):

To make it a bit clearer, this is a diff of the two outputs:

    58a59
    > [Pipeline::Dispatch] dispatching to Pangloss::Segment::ListConcepts
    73a75
    >         view
    75a78,80

    >         concepts
    >         concepts_collection
