###!!! ASSERTION: unexpected frame type: 'Not Reached', file /Users/jruderman/trunk/mozilla/layout/base/nsCSSFrameConstructor.cpp, line 10673

###!!! ASSERTION: Backing up twice; this should never be necessary: '!forceBreakInContent', file /Users/jruderman/trunk/mozilla/layout/generic/nsBlockFrame.cpp, line 3242

Might be related to bug 413582, which triggers the first assertion but not the second.
WFM.  Just triggers a warning now:

WARNING: We shouldn't be backing up more than once! Someone must have set a break opportunity beyond the available width, even though there were better break opportunities before it: file /Users/jruderman/central/layout/generic/nsBlockFrame.cpp, line 3451
