While this doesn't crash on connect in the r32901 nightly, it does cause other Bad Stuff™ to happen: namely, the remote window area turns white after switching tabs and then going to switch monitors (on a dual monitor system) *will* cause it to crash.

[Gerard Iglesias]

At this time, with the build r40351 it does crash WebKit
