Bug#709846: synaptic: Download status column vanishes when downloads begin

[Alex Vanderpol]

I finally managed to get a window where the download status column is 
visible before any files have started downloading, I'm attaching a 
screenshot of this so you can compare it with the one in my previous 
message and see exactly what I'm talking about.

Hopefully once you can see the problem in question you might be able to 
target it and possibly fix it, assuming it is related to Synaptic and 
not a GTK3 issue of some sort preventing that particular widget from 
being drawn (and somehow taking the whole column out with it).
