	Hi,
getting backtrace from a flatpak is tricky, to say the least, but I
guess there will be something shown on the terminal when you run
Evolution from it, like:

   flatpak kill org.gnome.Evolution
   flatpak run org.gnome.Evolution

Does a similar problem happen when you run:

   [host]    flatpak run --command=sh org.gnome.Evolution
   [flatpak] xdg-open https://www.gnome.org
   [flatpak] exit

It probably should work, because it's not using gtk3 to open the URL.
Evolution did not change anything in how the URL-s are opened for many
years, can be a decade, thus it's something either with underlying
libraries (gtk3, glib), or with the portals, or something with the
machine settings.

These commands (ran in your terminal, not in the Flatpak sandbox) can
show you which apps the glib knows about to be used for the respective
URL scheme:

   gio mime x-scheme-handler/https
   gio mime x-scheme-handler/http

It returns here:

   Default application for “x-scheme-handler/https”: org.mozilla.firefox.desktop
   Registered applications:
	org.gnome.Epiphany.desktop
	org.mozilla.firefox.desktop
   Recommended applications:
	org.gnome.Epiphany.desktop
	org.mozilla.firefox.desktop

It's possible gtk3 failed to show/open the URI, but did not set an
actual error message, which leads to a NULL dereference and then into a
crash. I made a change [1] to cover this case, but I cannot tell
whether it would help you at all, because it's not known where
precisely it crashed for you.

	Bye,
	Milan
