Comment 13 for bug 1813471

I've experienced this same crash with Thunderbird 60.5.1 from the mozilla team's ppa on Ubuntu 18.10.

In my case, I had to first add a mail account and when autoconfiguration was complete and I hit done/continue thunderbird crashes. Any subsequent launches result in a crash until the cache+profile is removed (I'm not sure if removing both is necessary but it works).

un-setting GTK_USE_PORTAL and then launching thunderbird seems to work (no more crashes).
