I was running on a RedHat 6.0 system when I got this error. The program printed this out a bunch of times. ##!!! ASSERTION: invalid col span or col index: 'effColSpan > 0', file ../../../../../mozilla/layout/html/table/src/nsCellMap.cpp, line 1100 ###!!! Break: at file ../../../../../mozilla/layout/html/table/src/nsCellMap.cpp, line 1100 Then it generates a SIGSEV.
