I have seen this 4 times today already, all while reading news with Gnus. I am not yet sure of circumstances; it is surely not directly reproducible. But the last 2 times, when I was especially aware of what had just gone down, it was when leaving groups that had just displayed MIMEd HTML content. That is, that's where I've noticed it, though I have no idea whether MIMEd HTML is relevant to the death. A sample error being generated is Error: Widget *Article* has zero width and/or height which is a fairly fascinating assertion on Xt's part. Next time it happens, I'll leave the dying XEmacs around, stuck in gdb, so I can poke at values in which it believes; I would welcome suggestions for particular items to look at. I will note, however, that it looks like "tabs" are guilty yet again (frames 11 & 17), and I notice rather a lot of tab flickering (highly annoying, regardless of relative bugginess) as I move from group to group. There are few matters of programming which annoy me more than library functions which unilaterally conclude to exit the process. Xt sucks. RH6.0 + 2.2.12 + XFree 3.3.5. Installation file at bottom.
