CC'ing troy because I'm not sure if this has anything to do with his recent checkin for layout contraints. It seemed to work fine yesterday. Here's my stack trace: nsDebug::Assertion(const char * 0x006446b8, const char * 0x006446a4, const char * 0x00644670, int 3309) line 95 + 13 bytes nsTableFrame::GetColumnWidth(int 0) line 3309 + 34

This is basically crashing every page on the net that uses tables... Upping priority.‰

Must have been a problem with my build. I blew away my tree and repulled and built and it works fine now. Sorry for the false alarm.‰

Verifying as invalid, since the current builds load www.netscape.com just fine.
