Everything using chromium/seccomp jailing breaks currently including chromium due to missing IA-32
rules in libseccomp and/or chromium itself.

Firefox seems to work fine.
epiphany works.
midori works.
luakit works.

Chromium crashes with sigsegv (I would expect something which reminds me of a seccomp syscall?).

konqueror, falkon, qutebrowser are based on qt5-webengine. They all open up but then don’t render a page (issuing the seccomp error messages attached below).

vivaldi the same, but as it is closed source, we cannot fix it.
