<pre>Hello.
I found that WebKit2 (not sure if it is WebKit2Gtk but I use it) crashes when receiving a sighup signal.
This even affects Epiphany where the application completely crashes, hence the Critical severity.
I don't know a simple way to reproduce the bug, so I post the way I can always reproduce the issue:
1. Configure the newsbeuter RSS client to use epiphany (put `browser "epiphany %u &"` in `~/.config/newsbeuter/config) and at a least a feed URL in `~/.config/newsbeuter/urls`.
2. Run the command `urxvt -e newsbeuter` from the terminal.
3. Open a feed (with Enter), then a link (with O — capital o): this will open epiphany.
4. Exit newsbeuter (by hitting twice q): this will make epiphany crash.
Note that I do not get this issue if I run the command `newsbeuter` instead of `urxvt -e newsbeuter`.
This issue does not happen in other web browsers.
While debugging the web process with gdb, I see the following:
[Thread 0x7fde77556700 (LWP 9825) exited]

[Thread 0x7fdedf0159c0 (LWP 9805) exited]
At first, I thought it has something to do with gdbus (because I sometimes saw the message "Thread gdbus exited" or something similar), but the MiniBrowser also has this issue and I don't think it uses gdbus.
If you are unable to reproduce this issue or want more information, feel free to ask.
I run ArchLinux with
epiphany 3.22.1
webkit2gtk 2.14.2
Thanks to fix this issue.</pre>
