Well, the numbers indicate that while the query in the backend is returning
all 150 programs, only 4 rows (4*47+1 = 189) are being sent in the protocol.

I am trying to figure out how to blame this on my own mods to the database,
which add a "suggested" column to the various recording tables, could be causing
this.  I have removed my patches for this test compile, so it must be the extra
column in the database itself.  I thought myth was robust over there being extra
columns in some of the tables to allow code to be tested like this...
(I am loathe to remove my columns quite yet)

I notice that recordedprogram has only 146 entries while recorded has 150, but
the query is returning the 150 results, it's the converting them to programinfos
and spitting those out that is somehow aborting.
