akregator has taken up the task of crashing about half the time, again. i guess it just needed some time to settle, after having the debug packages installed.
i reported the bug. it was a duplicate of bug #382575, which is actually a bug with Qt (which i always thought stood for “QuickTime”, but, apparently, i’m wrong), and it was originally reported in july of 2017. it will be fixed… eventually… 😒
