I wouldn't be surprised if this were part and parcel of the other problems that you already know about; if so, I apologize.
But this looks like a separate bug, so I'll report it here. I was playing with the "Customize Results" adding a column displaying all shield's base block chance (NB: Not an affix)
The search succeeded, but in the block chance (Min and Max) columns, it had this instead of values:
Notice: Undefined index: blockChanceMin in /var/home/diablo3/public_html/db/templates/t_advList.php on line 117
I haven't experimented with other columns, so it might just be blockChanceMin and blockChanceMax, or it might be a problem with other columns as well.
