This is how Soprano (and with it Nepomuk) goes down when run against Redland 1.0.9:
symbol lookup error: /usr/lib64/redland/librdf_storage_sqlite.so: undefined symbol: librdf_storage_register_factory
Redland 1.0.8 works without problems. This is mainly for informational purposes and to propose to distributors to downgrade. I will also post a bug report with Redland and try to figure out what the problem is. But in the meantime it might make sense to not live on the edge for once. ;)
