bad_history

[John Newman]

After I switched my server over to 2.3.0 I started seeing quite a few
log entries like this:

Nov  1 10:34:10 news2 nnrpd[3236]: [ID 178959 news.error] cust-93-6.blah.com bad_history at 0 for  in E862E0C79C095D028938A87061420F4C

It looks to be the same few customer IP's generating these log entries
over and over.  From briefly looking at the source am I correct that
this is an issue with a broken news client on their end?  Is this
anything I need to worry about?
