[O] Setting user-defined properties while ido-mode is active

[Thorsten Jolitz]

Hi List, 
I copied the "ido everywhere" approach from Bernt Hanson's setup and it
works really great (especially using 'M-x' becomes so fast that
remembering all that keychords seems less necessary). 

However, I have to deactivate ido-mode everytime I want to set a
user-defined property with C-c C-x p, since ido-mode shows me all the
predefined property names and does not let me enter my own property
name.

Did anybody else experience this, or am I simply ignorant of some basic
ido-mode functionality here?
