New description:

 This is more or less related to #3000

 Calling

 {{{
 qgis.utils.iface.activeLayer().dataProvider().maximumValue(2).toString()
 }}}

 from QGIS' Python console does not reflect change in data. The shapefile
 must be loaded again, to get correct min or max.

 minimumValue() is also affected, but featureCount() works! I would expect
 them all to work without the need to reload the layer. I don't know,
 whether other formats are affected.
