title: Xdebug loaded correctly in Ubuntu but var_dump/error handling not being over-ridden
body: <p>I have recently upgraded to Ubuntu 10.04 and as usual installed xdebug from the package manager. I've never had a problem after that with getting the formatted error messages and var_dumps to show up but this time they don't.</p>
  
  <p>I ran phpinfo() and it is definitely loading it, and I even tried running some of the custom xdebug functions and all is working fine, but when I do a var_dump it comes up as though xdebug isn't installed. Any ideas why this is happening?</p>
