Attachment: testcase

Loading the testcase triggers a bunch of NS_UNCONSTRAINEDSIZE assertions, such as:

###!!! ASSERTION: shouldn't use unconstrained widths anymore: 'availableWidth != NS_UNCONSTRAINEDSIZE', file /Users/jruderman/trunk/mozilla/layout/generic/nsHTMLReflowState.cpp, line 295

nsFrame::RefreshSizeCache is calling BoxReflow() with an unconstrained pref size:

5782        rv = BoxReflow(aState, presContext, desiredSize, rendContext,
5783                       rect.x, rect.y,
5784                       metrics->mBlockPrefSize.width, NS_UNCONSTRAINEDSIZE);
(gdb) p metrics->mBlockPrefSize
$7 = {width = 1073741824, height = -1}
