It seems to segfault when it encounters some messages but not others,
and *appears* to be more likely to happen if there are more posts in a
newsgroup. I was able to select and read a newsgroup with only two
posts, exit that group, select another one with 50 or so posts, read
one post and then it segfaults. Selecting a group with say 200 posts
and it segfaults on the first post.
thanks,
