the workunit0 file seems mostly a valid list of urls and agent
information, but is only 20kbytes of size and at the end it seems cut
off or something.

the last block of crawling information ends with
> User-Agent: GrubNG

all other blocks of crawling information seem to have:
> User-Agent: GrubNG 20080128

maybe the clients should validate the workunit files and/or
delete/refetch workunits if there seem to be errors or something. dont
know if this is the reason for the crash.

the last character in the workunit is a space " " after the "GrubNG"
