Comment 4 for bug 1349510

The browser crash is bug 1337338, but the real problem here is that the renderer is terminated because it sent a message that can't be serialized (from comment 2):

[0728/131359:ERROR:render_process_host_impl.cc(1437)] bad message 65594 terminating renderer.

Message 65594 is OxideHostMsg_GetUserAgentOverride. My guess is that the renderer is sending a URL that exceeds 2*1024*1024 characters, which is the limit at which the GURL ParamTraits specialization will fail to serialize the url parameter required for determining the navigator.userAgent override for the page
