Some time ago, the Dot changed its feed's URL. I have a couple of unread articles there, but I also want the new articles. I edited the feed address, and indeed got the new items; but, when this happened, the last of my old unread articles was marked "read". So I selected it and pressed control-U to mark it unread again; this resulted in the following crash:

Application: Kontact (kontact), signal SIGSEGV

When I re-opened Kontact, the feeds were back as if I'd never edited anything, so I repeated the process with the same results.

This may be related to bug #190059.

Thanks,
Shai.
