The tab does not crash when visiting static pages like my blog at
https://elephly.net.  It looks like it reliably crashes on sites that
use transparent elements; ctrip.com, for example, loads fine until it
begins running JavaScript to display a semi-transparent banner.

=E2=80=9Cdmesg=E2=80=9D shows me a couple of lines that indicate that the i=
915_dri.so
driver segfaulted in processes like =E2=80=9CWeb Content=E2=80=9D or =E2=80=
=9CWebKitWebProcess=E2=80=9D.
That library is provided by the =E2=80=9Cmesa=E2=80=9D package.

I=E2=80=99m currently using mesa 17.2.1 on this machine.  I still have a co=
py of
17.1.4, so I preloaded it and started icecat: it did not crash!

I did the same to epiphany, but it complained about failing to load the
driver.

Mesa 17.2.1 has a broken i915_dri.so driver.

This might be interesting: it seems that in Epiphany only pages with
non-trivial JavaScript are affected.  The tab does not crash when
visiting static pages like my blog.

This is the same in Epiphany and Icecat.

Here=E2=80=99s a backtrace when running icecat in a gdb session.  The crash
reliably happens when visiting ctrip.com:

Can you grab backtraces so we have an idea where this happens?  It could
be something in a support library like GTK+, Freetype, and whatnot.

Unfortunately, they both are affected.

It=E2=80=99s not just webkit: Icecat tabs also crash *a lot*.  Also here it=
=E2=80=99s
both grafted and ungrafted browsers.

I wonder if this is related to the Emacs crash (which only appears with
the grafted Emacs on i686).
