too little horizontal space for galley

[Thomas McDERMOTT]

Lout-ers,
        I'm getting the following error from lout 3.12:

2,1: size constraint 14794.722c,15.989c,14794.722c broken by 0.000c,60.242c
2,1: size constraint 14794.722c,20.988c,14794.722c broken by 0.000c,60.289c
2,1: too little horizontal space for galley @ReportBodyWithoutCoverSheet at 
@Galley
lout:
         internal error: assert failed in AdjustSize: f < 0!
Abort (core dumped)

My question is: How do I go about finding the part of the document
that's causing the problem? Can I do better than deleting random
sections of the document until the problem goes away? It _seems_ that
the problem isn't actually on line 2, column 1...That's just @Report.

Cheers,
        Tom
