Bug#910852: libqt5webengine5: Akregator crashes very often, WebEngine related
Package: libqt5webengine5
Version: 5.11.1+dfsg-5
Severity: serious
Justification: crashes make Akregator almost unusable
Dear Dmitry,
I found Akregator crashing very often when accessing articles as webpages
which are rendered by Qt WebEngine. These may also be related to KDEPIM
18.08 update. Please reassign if needed.
I downgraded libqt5quick5 to 5.11.1-5 due to the hint in
#910317: libqt5quick5: Sefault in applications using QWebEngineView
https://bugs.debian.org/910500
However this did not help. Thus I installed debug packages to retrieve a
useful backtrace.
Steps to reproduce:
- Start Akregator
- Open articles in a few feeds (I used feeds from pro-linux.de, heise.de/open
and various Debian related and other feeds, I bet it does not matter all
that much which ones)
- Click around in those articles, follow links, close QtWebEngine rendered
articles
Basically I just "use" Akregator as usual and it usually crashes within 5
minutes. I have also seen crashes in KMail after having rendered HTML mail.
I did not yet generate a backtrace from those.
Often I see this "A parser-blocking, cross site" message on console. I do
not know whether this is related. I'd love to use uBlock Origin with my
hardened settings within Qt WebEngine to get rid of that advertising
and tracking crap.
