I've removed listfiles in /var/lib/apt/lists/, then start synaptic. It
fails to build cache (inside libapt-pkg) and at pkgcachegen.cc:669
return false;.
Next, pkgMakeStatusCache returns false.

Next, at RPackageCache::open(OpProgress&):
 if (_error->PendingError())
     return _error->Error(_("The package lists or status file could not
be parsed or opened."));

Next, at RPackageLister::openCache(bool):
        if (!_cache->open(*_progMeter))                                 
                        
            return false;                                               
                        

And finally in main() we have exit.
