// In Chrome, ex.stack contains a stack trace as a string. Cite from http://code.google.com/p/v8/wiki/JavaScriptStackTraceApi follows:
//
// By default, almost all errors thrown by V8 have a stack property that holds the topmost 10 stack frames, formatted as a string. Here's an example of a fully formatted stack trace:
//
// ReferenceError: FAIL is not defined
// at Constraint.execute (deltablue.js:525:2)
// at Constraint.recalculate (deltablue.js:424:21)
// at Planner.addPropagate (deltablue.js:701:6)
// at Constraint.satisfy (deltablue.js:184:15)
// at Planner.incrementalAdd (deltablue.js:591:21)
// at Constraint.addConstraint (deltablue.js:162:10)
// at Constraint.BinaryConstraint (deltablue.js:346:7)
// at Constraint.EqualityConstraint (deltablue.js:515:38)
// at chainTest (deltablue.js:807:6)
// at deltaBlue (deltablue.js:879:2)
//
// If all the above information is available a formatted stack frame will look like this:
// at Type.functionName [as methodName] (location)
// or, in the case of a construct call:
// at new functionName (location)
// If only one of functionName and methodName is available, or if they are both available but the same, the format will be:
// at Type.name (location)
// If neither is available <anonymous> will be used as the name.
// One special case is the global object where the Type is not shown. In that case the stack frame will be formatted as:
// at functionName [as methodName] (location)
// The location itself has several possible formats. Most common is the file name, line and column number within the script that defined the current function
// fileName:lineNumber:columnNumber
// If the current function was created using eval the format will be
// eval at position
// where position is the full position where the call to eval occurred. Note that this means that positions can be nested if there are nested calls to eval, for instance:
// eval at Foo.a (eval at Bar.z (myscript.js:10:3))
// If a stack frame is within V8's libraries the location will be
// native
// and if is unavailable it will be
// unknown location

// Examples:
// at http://my.ivideon.local/:132:67
// at Error.<anonymous> (eval at declareErrorClass (http://my.ivideon.local/static_src/ivideon/components-base/js/ivideon.utils.js:181:23))
