NullPointerException during Fetch

[jim shirreffs]

You can get much better and more detailed information in the log files. Have 
a look at them for better clues as to what when wrong. Null Pointer 
Exceptions can come from just about anywhere. Also the fetching continued so 
the failed fetches might not be a big deal. Check out the log files to see. 
Also try pasting the failed url into your broswer and see what happens.

hope this helps
