After my first typo since updating dependencies, I noticed fatal errors were displayed in a symfony layout, unfortunately I'm getting displaying issues.

The first issue occurs because I don't have xdebug installed, apparently it has only been tought for xdebug (http://easycaptures.com/fs/uploaded/737/5939488074.png).

The second issue occurs because the register method of the ErrorHandler is called twice, I can't investigate on why now (but I don't touch it myself and don't have that many third party bundles installed, fostwitterbundle and genemubundle only), which causes the shutdown function being registered twice.

A quick fix for the first issue could be to set display_errors to false on debug mode, as apparently all kind of errors would now be displayed by symfony anyway.
