[imp] "Attach your contact information to the message"

[Liam Hoekenga]

I'm trying to use the "Attach your contact information to the message"  
feature in IMP 4.3 / Turba 2.3.  I've gone into turba, created an  
entry for myself in my addressbook, and the selected "Mark this  
contact as your own."

Turba replied with..

     This contact has been marked as your own.

But when I then try to use "Attach your contact information to the  
message?", I get..

     * You didn't mark a contact as your own yet.

It's a normal sql based addressbook.  I don't see any configuration  
options or preferences that seem applicable.

Any ideas as to why this isn't working?
