[Flash] Crash while jumping forward in a YouTube video

[spaeps]

I'm referring an issue reported on the Arch Linux BTS [1].

Qupzilla (Qt5) crashes when jumping forward in a YouTube video,
in a point not already loaded.

The Qt4 build is not affected by this.

Probably related to qt5-webkit since otter-browser (using Qt5)
is affected too.

I am able to reproduce this issue with

QupZilla (Application version: 1.9.0 (ce528cf), Qt version: 5.4.0, WebKit version: 538.1)
QtTestBrowser (Qt version: 5.4.0, WebKit version: 538.1)

Since this is a QtWebkit issue it will not be fixed in QupZilla. Thus, I have opened an issue upstream. Maybe you want to have a look at the issue status on QTBUG to close your issue on archlinux as well, once it is fixed upstream.

This already merged patch solves the issue (that's not included in the 5.4.0 alpha):

@spaeps: Is it safe to close this issue?

I've been getting crashes watching flash videos on YouTube. I wasn't jumping forward, I was just watching it...

Here's the last video I was watching that generated this crashlog;

QupZilla just crashed when I went to speedtest.net.

Seems like there's a lot of crashes going on related to flash...

This issue is fixed upstream, but as far as I understood, the solution will be in 5.4.0 RC. They do not plan a version 5.3.3.

Ok...

Please update your QtWebkit as this issue does not longer happen with the latest version.
