[Qgis-user] problem with GRASS custom variables

[Martin Landa]

Dear QGIS users,

I have problem setting up custom GRASS-related variables in QGIS settings
(use custom variables):

Unfortunately after restarting QGIS the statement below in Python Console

from grass.pygrass.gis import Mapset

fails with

ImportError: Could not load grass_raster.8.4.

When I set the same environmental variables before starting QGIS from shell
than the pyGRASS statement *works*:

GISBASE=/home/martin/src/grass/dist.x86_64-pc-linux-gnu
PYTHONPATH=/home/martin/src/grass/dist.x86_64-pc-linux-gnu/etc/python
LD_LIBRARY_PATH=/home/martin/src/grass/dist.x86_64-pc-linux-gnu/lib qgis

Any idea why custom variables defined by QGIS settings fail in this case?
Why are they behaving differently from environmental variables defined in
the shell?

Thanks in advance, Martin
