[QGIS-Developer] Issue reading world_map.gpkg

[afernandez]

Hello,
I'm trying to automate changes in the projection used by the map canvas. If 
I open the python console and use the following command sequence:
novus_CRS = '+proj=lcc +lat_1=63.0 +lat_2=75.0 +lat_0=70.0 +lon_0=-97.0 
+datum=WGS84 +no_defs'
crs = QgsCoordinateReferenceSystem.fromProj4(novus_CRS)
qgsProject = QgsProject.instance() 
qgsProject.setCrs(crs) 
This works fine. However, and when I try to incorporate it programmatically 
(e.g. in a plugin), I keep getting the error:
Failed to open /usr/local/share/qgis/resources/data/world_map.gpkg
However, this file seems to be in the right subdirectory:
$ cd /usr/local/share/qgis/resources/data
ubuntu at ip-172-31-23-167:/usr/local/share/qgis/resources/data$ ls -l
total 12744

Not sure why of this behavior discrepancy console vs. programmatically. 
Thanks.
