Fwiw, seeing this all the time in Fennec (on startup/resizing window, etc)
Still asserts on trunk:

ASSERTION: bad inline size: 'metrics.ISize(lineWM) >= 0', file /builds/slave/m-cen-l64-d-000000000000000000/build/src/layout/generic/nsLineLayout.cpp, line 1039

ASSERTION: bad block size: 'metrics.BSize(lineWM) >= 0', file /builds/slave/m-cen-l64-d-000000000000000000/build/src/layout/generic/nsLineLayout.cpp, line 1040

ASSERTION: illegal width for combined area: 'aOverflowAreas.Overflow(otype).width >= 0', file /builds/slave/m-cen-l64-d-000000000000000000/build/src/layout/generic/nsLineBox.cpp, line 545

ASSERTION: illegal height for combined area: 'aOverflowAreas.Overflow(otype).height >= 0', file /builds/slave/m-cen-l64-d-000000000000000000/build/src/layout/generic/nsLineBox.cpp, line 547
