When running Epiphany 3.20 backed by WebKit2Gtk 2.12.0-1 in Arch Linux, it crashes with a certain frequency because it calls X11 code. Some websites where the crash occurs: - Slack (only when logged in) - UOL: www.uol.com.br Looks like the JavaScriptCore component is the one to blame here. A not-so-useful stacktrace: Thread 1 (Thread 0x7ffff7f0e980 (LWP 18930)): #0 0x00007ffff7ad90c9 in _XSend () from /usr/lib/libX11.so.6 #1 0x00007ffff7ad94d5 in _XFlush () from /usr/lib/libX11.so.6 #2 0x00007ffff7adbfa5 in _XGetRequest () from /usr/lib/libX11.so.6 #3 0x00007ffff7ac0225 in _XGetWindowAttributes () from /usr/lib/libX11.so.6 #4 0x00007ffff7ac0421 in XGetWindowAttributes () from /usr/lib/libX11.so.6 #5 0x00007ffff26ee864 in ??

Unfortunately this backtrace is mostly useless, except to show that JSC is definitely not to blame. We really need a backtrace with debug symbols and preferably stack variables ('bt full').
This issue doesn't happen anymore with Epiphany 3.20.3 and WebKitGTK+ 2.12.3.
