Robert, could you add some more details, in particular

* XEmacs configuration information (e.g., a copy of the Installation
file, if you built XEmacs yourself)
* what you're using to read (Gnus? which version?)
* which blog entry you were reading

I just glanced through the entries for 29 February through 2 March
(gwene doesn't show any for 3-4 March), using Gnus 5.10.8 on XEmacs
21.5.31+0df3cedee9ac, x86_64, and I don't get a crash.
