You likely hit http://hub.qgis.org/issues/12264 / 
https://github.com/qgis/QGIS/commit/f106a2ef999224f1f1b7f214d08b039749d6111b

Has been fixed in master, but not backported yet in 2.8 branch AFAICS

Possible workaround if you're stuck. Use output of "gdalwarp your.png out.tif" 
or "gdalwarp your.png out.vrt -of VRT"
