[erlang-bugs] Observer table viewer crash - Patch???

Hi,
It should be off by default of course. But I found that by not setting the tuple {true,Time} or {false,Time} in observer_tv_table.erl would cause it to crash.
In my case the tables are quite small, so having a refresh every 20 seconds is pretty painless. Of course, for large tables I can see that you might want to warn the user that it's a really bad idea.
Thanks
Matt
