The latest nightlies seem to crash if you try to make a selection with flash on the same page. Go to the URL and try to select the sidebar - from the description down appears to work best. (If that doesn't work, starting the selection from Related/More from this user/Playlists also seems to do it). WebKit will crash. This appears to be the relevant part of the crashlog, but I'll upload the full thing in a second. 0x011bf194 WebCore::RenderLayer::autoscroll() + 308 0x012513ac WebCore::TimerBase::fireTimers(double, WTF::Vector<WebCore::TimerBase*, (unsigned long)0> const&) + 156 0x01251440 WebCore::TimerBase::sharedTimerFired() + 112 I can reproduce this about 9 times out of 10, but it only seems to happen on YouTube (not Google Video or other sites with flash content), so I'm going to leave this as unconfirmed for now to be safe.

I cannot get this bug to reproduce. Any more hints, anyone?
I can't reproduce this anymore either.
I can no longer reproduce this either.
Okay, let's close this for now, then. If anyone can reproduce, say so!
