[Qgis-developer] QgsSpatialRefSys::epsg() for user defined CRS

[Marco Hugentobler]

Hi all,

I noticed that the function QgsSpatialRefSys::epsg() returns strange values 
for layers with user defined CRS (probably mEpsg not initialized). What 
should we do in such cases? Is there an EPSG number for unknown crs or user 
defined crs?

Thanks,
Marco
