 To reproduce this bug, follow the following steps:
 1) Extract and load the vrt file that is attached to this ticket
 2) probe raster to see where the nulls are located.
 3) zoom into a region that has some nulls.
 4) In Raster Layer Properties>>Symbology, click on Current extent and then
 the Load button.  The vrt nodata value (-999) shows up in Min.

 If you zoom into an area where there are no nulls, you get a correct
 min/max value.
