When using phpMyAdmin in firefox and Chrome in Ubuntu 9.10 the main content area iframe often fails to load - leaving me with a blank white content area (though the sidebar is still there).
Firebug reports that the iframe or AJAX response makes it back - but it fails to load in the iframe area. It seems to be tied to the SQL queries I try to run as just clicking normal links like table names works.
My guess is that both browsers may be choking on a bad response from phpMyAdmin - or maybe the sessions it uses are messing up causing die()'s or something on the PHP side. I think I remember something about Ubuntu's /tmp being locked down...
Here's a copy of the response I get in firebug.
