(linux) qgis crashes when opening a saved project with a GRASS raster and reprojection enabled

[lutra]

I have see this under ubuntu linux and qgis trunk, not under windows xp.

Steps to reproduce:

*) create a mapset with a projected crs (I tested with epsg 3003 and 3763)

*) in the qgis project properties choose the (same) crs and enable on the fly reprojection

*) add GRASS layers, at least one of them raster (with just vectors no problem)

*) save the project and close qgis

*) open qgis and try open the saved project, qgis will crash with

Error: 
	GDAL Error 6: No translation an empty SRS to PROJ.4 format is known.
Segmentation fault

Apparently this bug is gone in recent revisions.
