[Qgis-developer] saga raster calculator fails

[matteo]

Hi guys,
trying to do a simple operation with the saga raster calculator (qgis
master vesion):
* geotiff dem
* ifelse(a>500,a,0)

saga throws me an error due to some prj4 issue.. ideas?!
Am I missing something?

Thanks

this is the error and the complete log:
