Bug report #10467
QGIS master uses column aliases for symbology (and it returns no values)

In QGIS master when a column alias is defined this does not only replace the column name in the table of attributes (as it always happened in QGIS since aliases where introduced), but also in the dropdown used for categorized/graduated symbology.
One problem: clicking on "classify" after choosing an alias no symbology categories are created (it shows only the generic one that qgis always adds at the end of the symbology classes list).
Second problem: removing the alias does not solve the issue, in fact after removing it ("fields" tab) the dropdown for categorized/graduated symbology has a blank space where the column name should show. The only way to "fix" is removing the layer.
