I see that 0.96 already has this patch, and it's behavior
is slightly different but no better, alas:

(pan:20105): GLib-CRITICAL **: g_utf8_casefold: assertion `str != NULL'
failed

(pan:20105): GLib-CRITICAL **: g_utf8_collate_key: assertion `str !=
NULL' failed
<hundreds of pairs of lines identical to the above snipped>

I'm guessing that those GLib-CRITICAL messages appear once for
each article in the group now, instead of just once, before the
segfault.  The backtrace is much different this time, so I'm
hoping it will be more helpful.

BTW, I emailed you the file at your rebelbase.com address.
