[Bug 1066046] Re: pvr driver crashes when ubiquity-slideshow starts

[Mairo Pedrini]

Is there a stack trace of the crash? I am curious if this could be the
same issue I'm seeing with a powerpc machine. Some pages (sourceforge's
project page, for one) crashed midori, uzbl and GtkLauncher, and upon
examining the stack trace, found it to be in libjavascriptcoregtk. Sorry
if this is the wrong place to ask.

Bug description:
  [ Description ]

  I think this happened on any page which uses JS. An upstream bug
  (linked from here) in the JS JIT results in segfaults.

  [ Test case ]

  On an armhf machine, try

    /usr/lib/webkitgtk-3.0-0/libexec/GtkLauncher
  "http://news.bbc.co.uk/"

  it should briefly open a window and then segfault before the fix, and
  successfully load the webpage after.

  Also try the slideshow that prompted this bug report in the first
  place

    bzr branch lp:ubiquity-slideshow-ubuntu
    cd ubiquity-slideshow-ubuntu
    ./Slideshow.py --path=build/ubuntu --controls

  again you should see a segfault (coming from webkit) before, and a
  lovely slideshow after.

  [ Regression Potential ]

  This might make webkit a bit slower on armel/hf. It shouldn't be too
  bad, but perhaps exercise a bit by browsing around in epiphany-browser
  to see.
