Description Sishun Liu 2020-03-23 03:06:30 UTC 
Today I was reading a blog about Emacs from my Emacs RSS. The blog link is "https://cestlaz.github.io/post/using-emacs-69-floobits/". Then I clicked the "watch in Youtube" button in the small video player in akregator and it crashed immediately. I have already tried several times and this problem appears every time.

STEPS TO REPRODUCE
1. Open the given link in akregator.
2. start playing the video and click the "watch on Youtube" button.

OBSERVED RESULT
Akregator crashes.

EXPECTED RESULT
Akregator should not crash.

SOFTWARE/OS VERSIONS
Linux: Arch Linux@5.5.10
KDE Plasma Version: 5.18.3
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.1

Here is the trace.log catched by gdb. I created this file following https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces for the bug reporter didn't catch any backtrace information about that.
