However, we still don't know why the source object is NULL (it should never be apparently). What we really need is a full core dump to analyze Given that this appears to be memory corruption, what we really need is enough information to *reproduce* the problem as a core dump is likely to only show that memory has been corrupted without giving us any hints to why.

Could you please check the timestamp of the crashfile, to verify whether this plymouth crash corresponds to the *first* boot after install, or the second?
