--- Comment #2 from Michael Catanzaro <mcatanzaro at redhat.com> ---
I just hit this crash on an internal Red Hat website, but wasn't able to reproduce it unfortunately. It would be easier to debug if it was reproducible. Anyway, my stack trace looks identical to the one you attached. Notably:

(gdb) frame 4
#4  0x00007f18c360d0a1 in ScriptMessageClientGtk::didPostMessage (this=0x7f18aa771840, serializedScriptValue=...)
    at /buildstream/gnome/sdk/webkitgtk-6.0.bst/Source/WebKit/UIProcess/API/glib/WebKitUserContentManager.cpp:411
warning: 411    /buildstream/gnome/sdk/webkitgtk-6.0.bst/Source/WebKit/UIProcess/API/glib/WebKitUserContentManager.cpp: No such file or directory
(gdb) print m_manager
$1 = 0x55c993bc4a10
(gdb) print ((GObject*)m_manager)->ref_count
$2 = 2863311530

2863311530 is notably 0b10101010101010101010101010101010, so clearly the WebKitUserContentManager is not valid. Should have used a smart pointer....
