[GeoNode-users] segmentation fault on saving maps (was error on saving maps, again!)

Tue Jan 12 07:00:05 PST 2016

Hi Eugenio,

the error could be this one

src/pj_gridcatalog.c: No such file or directory

which seems related to the PROJ.4/pyproj libraries.

Not sure what is wrong but try to reinstall them. Is the best I can tell :)

good luck
