Bug: Weblogsping/xmlrpc doesn't gracefully handle exceptions

I started getting this error in my logs a few minutes ago running the 
near latest cvs build. It's causing apache to throw an error page on any 
request (ie, pyblosxom has stopped working entirely). The root cause of 
the error doesn't have anything to do with pyblosxom (it's either my 
server or one of the weblog ping servers), but it seems to me that this 
type of exception should be caught and reported but shouldn't keep the 
pgae itself from getting rendered.
