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.
