CRM-16095 Civi warning when editing Drupal content

Can you please provide more details:

• What happens when you disable that module? Do the errors go away?
• Can you enable debug and backtrace to get more info?
• Can you provide steps to reliably reproduce?

• What happens when you disable that module? Do the errors go away?
  It is difficult to disable the module CiviCRM Contact Reference Field as it is used by several fields in several content. But if I remove the field > then the trouble is gone and I can edit the drupal content.

• Can you enable debug and backtrace to get more info?
  I install Devel but no I cannot see any information on the warning page. Only :
  Page execution time was 1161.33 ms. Memory used at: devel_boot()=9.08 MB, devel_shutdown()=82.72 MB, PHP peak=84.5 MB.

• Can you provide steps to reliably reproduce?
  As it is not immediate [at first everything works when using a field that reference a CiviCRM contact], I don't know yet what makes the bug happen.

In CiviCRM menu go to Administer->System Settings->Debugging and Error Handling
Please enable the debug mode and the "display backtrace".
Then try triggering the bug again and we can see if the error message is more helpful.

Thank you for the advice, so I enabled the backtrace.
That gave this :

OK This ought to fix it:

Thank you very much Coleman,

I test the fix in the 4.5.8 with affected Drupal content, and it works now. Perfect.
