Crash on armhf when starting playback of an embedded video

[Olivier Tilloy]

Testing webbrowser-app with the latest oxide built from trunk on a N7, going to youtube.com and trying to play back any video triggers the following crash:

Re-opening as I’m still seeing webbrowser-app crash when a renderer process is terminated, with a very similar stacktrace. See e.g. bug #1349510.

[Chris Coulson (chrisccoulson)]

It's the same crash, because the fix hasn't been uploaded in to the distro yet. Adding an Ubuntu task

[Olivier Tilloy (osomon)]

Oh, I thought it was in the 1.1.0 release already?

[Launchpad Janitor (janitor)]

This bug was fixed in the package oxide-qt - 1.1.1-0ubuntu3

---------------
oxide-qt (1.1.1-0ubuntu3) utopic; urgency=medium

  * Update to v1.1.1
    - Bump Chromium rev to 37.0.2062.58
    - Fix LP: #1337389 - Make ContentBrowserClient::CanCreateWindow work
      again
    - Fix LP: #1332996 - QtCreator often halts for a minute. Don't crash on
      Qt platforms that don't implement QPlatformNativeInterface. As we can't
      get a native display handle on these platforms, disallow any GL
      implementation in Chromium and guard against accesses to
      BrowserProcessMain::GetNativeDisplay()
  * Build with GCC 4.8 for now because GCC 4.9 breaks web content layout on
    the device, which sucks quite a lot right before RTM
    - update debian/rules
    - update debian/control

oxide-qt (1.1.0-0ubuntu1) utopic; urgency=medium

  * Update to v1.1.0
    - Bump Chromium rev to 37.0.2062.44
    - Fix LP: #1337338 - Don't crash when destroying a visible RWHV, which
      happens when a render process crashes
    - Fix LP: #1337890 - Update the power save blocker to use the Unity API
      on touch devices
    - Fix LP: #1338639 - Don't crash when calling WebView.loadHtml() before
      the webview is fully constructed
