Konqueror crashes only when using KHTML as a web engine. With QtWebEngine, the
underlying process runs out of memory without crashing the Konqueror.

KHTML:
Thread 1 received signal SIGSEGV, Segmentation fault.
Invalid permissions for mapped object.
0x00000008236c02f4 in KJS::JSObject::mark() () from
/usr/local/lib/libKF5JS.so.5

QtWebEngine:
