Performing "DELETE FROM games" on a table called "games", containing several rows, reports an error of "An unexpected error 0 occured." in the SQL pane, even though the delete executes correctly. Performing "SELECT * FROM games" on a table with zero rows reports an error of "An unexpected error 0 occured." in the SQL pane. In both cases, an error of "undefined" is also reported in the main error log pane at the bottom of the Web Inspector window.
Created attachment 21926 [details] Screengrab of the error. This JPG shows the error when performing a DELETE FROM statement on a table with several rows.
Just done a regression check, and the last revision in which this worked was nightly build r34753. It is broken as of r34798.
