I've seen recently a similar discussion on spatialite mailing list I think. If 
upgrading from spatialite 4.something to 4.1.2 or later, GDAL should also be 
recompiled so as to benefit from the spatialite_init_ex() functions

I don't recall the details but I somehow remember that one of the intermediate 
spatialite versions had an issue in its termination routine freeing the global 
GEOS context. I don't have any more problems with latest versions. But the 
debian ticket you mention seemed to be about a problem that arose with proj4 
update. Hum...
