> unexpected frame type

It's a LegendFrame.

Maybe what we should do here is only construct nsLegendFrames when the legend is in a fieldset, and otherwise just handle them by display type.  (Not sure how to deal with legends that aren't the first child, or multiple legends, though.)  We'd need to make sure legend is display:block in html.css in that case, though.
Then again, we should probably do that as a followup bug; nsLegendFrame is very similar to nsBlockFrame so we should just be able to add to CreateContinuingFrame.

We could certainly construct legends by display if the parent content is not a fieldset, sure.  That would make a lot of sense to me.

Legends that are not a first child of the fieldset we currently treat as "the" legend, and need to for web compat, iirc.

Multiple legends is tough if we ever continue kids of fieldsets; for that we need this continuingframe change.

Tomcat, you have a debug build. Can you verify this fix for

That's probably just an artifact of the testcase; the problematic code is there:  nsLegendFrame::GetType is implemented and CreateContinuingFrame doesn't deal with it.
