Python gnomekeyring.DeniedError when starting

[ideasman42]

When starting cgmail I get this error,
Im using a less privileged user account so there probably just needs to be a check for this and display an error dialog.

Traceback (most recent call last):
  File "/usr/bin/cgmail", line 18, in <module>
    a = AccountsWindow()
