Comment 1 for bug 1784580

I cannot type messages in evolution since the very latest update. Other fields work but trying to type in the main email box doesn't work. When trying to type for a minute, the window goes blank and shows an error bar with "Something has gone wrong with typing the message". I get a bug report popup about something having gone wrong with webkitgtk. I sent the report about it, but I'm not sure how to access that.
I have these versions of webkit stuff:

ii gir1.2-webkit2-4.0:amd64 2.20.3-0ubuntu0.18.04.1 amd64 Web content engine library for GTK+ - GObject introspection data
ii libqt5webkit5:amd64 5.212.0~alpha2-7ubuntu1 amd64 Web content engine library for Qt
