--- Comment #9 from Michael Catanzaro <mcatanzaro at gnome.org> ---
OK the problem is the network process crashes in a loop, but only in incognito mode. There's no rendering problem, just the page fails to load. We don't show any indication of page load state when there's only one tab, which is why I incorrectly assumed a rendering problem.
Backtrace is interesting. The crash is occurring deep inside WTF::parseES5DateFromNullTerminatedCharacters.
Program terminated with signal SIGSEGV, Segmentation fault.

That looked weird, and it doesn't look like the main thread either, so I decided to get a backtrace of all threads. Looks l ike many of them are all struck inside the same function, WTF::parseES5DateFromNullTerminatedCharacters:
