Hi Matteo

In Virtual Box, I installed Debian Testing, then upgraded it to Sid and ran
epiphany-browser 3.22.4-1. While it did not crash the system, no web pages
at all will load. On my host OS of Debian Testing, I did my weekly upgrade
and epiphany was upgraded to  3.22.4-1. When I loaded the NASA exoplanet
sim link, (eg https://exoplanets.nasa.gov/newworldsatlas/191/) I first got
the message:

Oops!
Something went wrong while displaying this page.
Please reload or visit a different page to continue.

So I reloaded the page. Bad Idea--my system locked up again! The output
from my logs being as follows:

Just as before

Epiphany is far from being my main browser, but Chromium locks up (although
at least not my whole system) when I just leave it to idle for ten or so
minutes on the espncricinfo.com site. The only reliable browsers in testing
for me are Firefox and Qupzilla. In regards to epiphany, I have purged my
host debian testing system of it.

All the best
