See http://bugs.webkit.org/show_bug.cgi?id=15976 and the layout test in LayoutTests/storage/transaction_callback_exception_crash.html When an exception is thrown from within a callback, there is no line number information in the console log. Why not?
Okay, I have looked at this. You don't get line/source information as you are throwing a primitive value which we cannot attach useful information to -- if you were to throw an object, everything should just work. If that is the case then this is a duplicate of bug #18855
I am now actually working on this. There was a wide spread of incorrect exception handling (in the sense that value conversion was bogus, and line numbers being lost).
Created attachment 22387 [details] Fix exception handling in the many places it wasn't correct.
