--- Comment #1 from Michael Catanzaro <mcatanzaro at redhat.com> ---
I'm going to close this because there's surely not anything WebKit can do if just querying the GL version string causes a crash.

First step here is to get a better backtrace. What we see above is not sufficient due to missing debuginfo. I'd want to see line numbers at least to know where exactly it is crashing. We have instructions here: https://handbook.gnome.org/issues/stack-traces.html

Once you've got a better backtrace, you can report to either the GLX provider (probably glvnd) or else the libc (probably glibc) depending on what the better backtrace reveals. What you've posted here *really* looks like a bug in dlopen() itself. That seems quite unlikely, but it's sure what it looks like.
