In this particular case, it was found that the first run of RCU failed, (e.g. in this case due to NLS setting), by default it rolls back. However this left tables in the Database. Even though subsequent RCU succeeds, corrupted tables are left in the Database which will cause Install or Upgrade issues.

This may not be the only errors we see as a result of this: Depending on why RCU failed the first time, and allowing the rollback and retry to continue will vary on errors and component being installed. (In general, allowing RCU rollback is not a good idea)
