[Qgis-developer] Postgresql layers not displaying?

[icosa atropa]

I just rebuilt from source on Ubuntu feisty following directions at
http://wiki.qgis.org/qgiswiki/BuildingFromSource.

New build runs fine - i connect to WMS layers, add and display vectors fine.
Problem comes in displaying Postgis layers.  The layers add just fine,
and I can even zoom to the layer extent and pull up the data table.
The layer just won't render, no matter what i do.

In the invoking terminal, I get the following messages, the first set
when I select the layer for display (from the legend), and the second
set when i unselect it:
