[Pkg-chromium-maint] Bug#891656: Adblockers fail to start

[fin4478 fin4478]

Package: chromium
Version: 65.0.3325.74-1 and others

Chromium from the Debian sid and experimental repository causes
adblockers to fail to start. Install one of these:
https://chrome.google.com/webstore/search/adblock

I have signal 11 SEGV_MAPERR  when logging
is enabled: 

xfce at ryzen5pc:~/Downloads/git$ chromium --enable-logging
--v=1
