--- Comment #24 from roded <webkit-bugzilla at rodedb.com> ---
Hi,
Giving it a shot with MiniBrowser, not sure I got this right, please let me know otherwise.

Executed /usr/lib/webkit2gtk-4.1/MiniBrowser --enable-sandbox and while it was loading, started gdb:

sudo DEBUGINFOD_URLS="https://debuginfod.archlinux.org/" gdb --pid=360894

This GDB supports auto-downloading debuginfo from the following URLs:
  <https://debuginfod.archlinux.org>
Enable debuginfod for this session? (y or [n]) y
Debuginfod has been enabled.
To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/usr/lib/libthread_db.so.1".
