Comment (by jchevali):

 Perhaps you'd like to deal with the assertion failed issue in the ticket
 that pege's opened, #28129 (although that same stack trace was presented
 here earlier), and leave this ticket for the other issues, namely, how
 should we investigate invalid descriptors (by the server that doesn't
 crash -- i.e., if given its characteristics, e.g., no GCC, no IPv4, etc.,
 you still deem it worthy of testing), and whether padded content should be
 allowed (after all under the base32 definition I believe it's legal), and
 whether padded entries or otherwise invalid entries (except comments)
 should, when they're not among otherwise valid entries, result in an
 unsecured service or a secured (closed) one.
