i.e. the code is found it the stellarium.core, but not in the executeable and
not in the shared libs;

Does stellarium uses dlopen(3C) to load additional shared libs?

I did in addition with the libs from the ldd output:

# for i in `cat libs` ; do echo grep $i : ; perl -e 'open(F,"<:raw", $ARGV[0]) or die $! ; while(<F>) { if(/\x66\x0f\x6e\xa4\x87\x08\x01/) { print "found ($ARGV[0])\n"; exit; }}' $i ; done
