Package: epiphany-browser
Version: 3.38.2-1
Severity: normal
Dear Maintainer,
When using epiphany-browser to access a web page that contains HTML5
video content, the browser crashes with a SIGSEGV.
Example of web page that crashes the browser is youtube, or an html5
video test page such as https://tekeye.uk/html/html5-video-test-page
This involves VA-API, I am not sure exactly where the root cause lies
but since the issue is manifesting while using epiphany-browser
specifically, I thought I would start by opening a bug here.
I also noticed that, while I have 2 devices running bullseye with
identical HW and both systems up to date, only one of the 2 device has
the issue. Those are Purism Librem 14 laptops, shipping an Intel UHD
Graphics 620 chip.
To be able to troubleshoot further the issue, I installed the following
debug symbols:
ii epiphany-browser-dbgsym 3.38.2-1 amd64 debug symbols for epiphany-browser
ii gstreamer1.0-vaapi-dbgsym:amd64 1.18.4-2 amd64 debug symbols for gstreamer1.0-vaapi
ii intel-media-va-driver-dbgsym:amd64 21.1.1+dfsg1-1 amd64 debug symbols for intel-media-va-driver
ii libdrm-intel1-dbgsym:amd64 2.4.104-1 amd64 debug symbols for libdrm-intel1
ii libva-wayland2-dbgsym:amd64 2.10.0-1 amd64 debug symbols for libva-wayland2
ii libwayland-server0-dbgsym:amd64 1.18.0-2~exp1.1 amd64 debug symbols for libwayland-server0
Note: I couldn't install dbgsym for libwebkit2gtk-4.0-37 since it is
installed from stable-security
