Description
When using the style dialogue to generate a graduated color ramp, there is a failure to properly recognize real numbers. A color ramp will be generated, but it usually fails to see any negative values. If I wrap the variable in a toreal() function, all works as expected. The dataset I'm having problems with is stored in PostGIS and the column is definitely real. I've seen this happen on a number of different datasets.
The dangerous bit is that the error is very quiet, as the color ramp is still generated, and most of the map still renders as normal.
Using ubuntu 14.04 and QGIS 2.8.1
(this is my first time reporting a bug. please be easy on my errors and omissions)

Can you share a sql dump of your dataset? Even a partial extract which demonstrates the issue will be useful.

I double checked, and this does indeed still cause the same problem for me.
