The new design at www.intel.com appears to be causing problems for mozilla. On a 5/2 cvs pull (post tree closing), I get pages of errors of this form: ###!!! ASSERTION: next frame in reflow command is null: 'nsnull != nextFrame', file /cs/src/mozilla/mozilla/layout/html/base/src/nsAbsoluteContainingBlock.cpp, line 337 ###!!! Break: at file /cs/src/mozilla/mozilla/layout/html/base/src/nsAbsoluteContainingBlock.cpp, line 337 ###!!! ASSERTION: null ptr: 'nsnull != aFrame', file /cs/src/mozilla/mozilla/layout/base/src/nsFrameList.cpp, line 306 ###!!! Break: at file /cs/src/mozilla/mozilla/layout/base/src/nsFrameList.cpp, line 306

Meant to say a 5/3 cvs pull (on solaris/native).

Fixed by Chris's checkin to nsAbsoluteContainingBlock
