Fast Downward chokes on some tasks

From Jendrik Seipp:
> I tried to run an experiment for all tasks currently in the planning.domains collection with Fast Downward. Unfortunately, there are many tasks which Fast Downward can't translate or validate. I have attached a file with the task names and the error logs. In most of the cases, the translator fails to translate the task. In tyreworld, VAL returns "Error in type-checking!". For all errors we need to know whether they are caused by limitations in Fast Downward and VAL or incorrect task specifications.
