If i do login/logout i can delete another addressbook.

Works for me, even on sogo-demo.inverse.ca.

I just had noticed the same problem and wanted to report it :-).

The following sequence is reproducible for me, even on sogo-demo:

• Go to Address Book
• Create two new address books and name them e.g., "abc" and "def" (this step is not necessary if you have two address books to spare)
• Delete one (e.g., "abc") and confirm the "Are you sure?" dialog (this works as expected)
• Delete a second address book (e.g., "def") and confirm the dialog
• The address book is still there (and it is not a display problem, as we will see later)
• Further attempts at deleting this or other address books will also fail silently
• Switch to another view (I used "Mail")
• Switch back to "Address Books" ("def" is still there)
• Now you can delete "def"
• But deleting another address book will fail silently unless you first switch the views again

So in summary, a single address book can always be deleted, but (without switching the view or a relogin), only one address book can be deleted
