Description Milan Crha 2023-06-21 07:15:08 UTC 
This is with epiphany-44.3-1.fc38.x86_64 . I start it and I'm greeted with a question whether I want to make Epiphany a default web browser, where I click "Yes" and get this crash:

/usr/include/c++/13/optional:477: constexpr _Tp& std::_Optional_base_impl<_Tp, _Dp>::_M_get() [with _Tp = MotionEvent; _Dp = std::_Optional_base<MotionEvent, true, true>]: Assertion 'this->_M_is_engaged()' failed.

Thread 1 "epiphany" received signal SIGABRT, Aborted.

No debug symbols, because I'm low on disk space and 2GB of WebKitGTK debug symbols is too much (I've like 700MB free space only, about which I'm notified whenever I log in (or in gdm, when I'm slow typing my password)).

Reproducible: Always
Comment 1 Milan Crha 2023-06-21 07:16:11 UTC 
I forgot the WebKitGTK version: webkitgtk6.0-2.40.2-1.fc38.x86_64
