Screencast of the bug (aka "You Won't Believe What Happens Next")

# Description:

Ok, that's weird. This webpage[1] (the whole website, actually) makes the tab to crash(?) and, wait for it, Chromium to be launched(!). See video as attachment for visual proof.

Always happens.
Happens in both Wayland and X sessions.
GPU is a G33, from a Pentium E5700 CPU.
Does not produce an ABRT thing, I don't know why.

I think it's not crashing, just *closing*. What happens if you have another tab open when you visit this website? I bet the browser remains open and only the tab that you used to visit this site closes, right?

Theory: I guess there is some bug in the download logic. Somehow the main resource is being improperly detected as a download, the tab closes itself, then Epiphany opens the "download" in the default URI handler (is Chromium your default browser?)

Yes.

Makes sense.

No. Web is the default.

Unfortunately I can't reproduce this :/

Really excellent bug though!

Weird.

Anyway, I tried to:

- Delete...
~/.cache/epiphany
~/.config/epiphany
~/.local/share/epiphany
~/.cache/webkitgtk
~/.local/share/webkitgtk

- and reset everything inside 'org.gnome.epiphany' in 'dconf-editor',

- and uninstall Chromium.

The thing still happens, however. Best hint I could find is this dialog from a "windowless" Files in a X session (see next attachment).

Dialog from a 'windowless' Files (just after the tab disappeared)

It says:

"Oops! Something went wrong.
Uncaught error message: no hostname specified"
