Huge (probably unintended?) debug output

ChunkFile(sc.p4k.getinfo('data/objectcontainers/pu/loc/mod/cave/rocky/rocky_lunar_01/rocky_lunar_01_s/rocky_lunar_unc_001_0_000/rocky_lunar_unc_001_0_000.soc'))

produces a huge debug output that is probably not intened? It is not immediately obvious where it is coming from (it is not a print())
