[turba] Invalid Address Book

[Helga Mayer]

Hello,

this has been probably asked before but I didn't find a working solution 
in the archives.
A particular user can't add contacts automatically to her standard 
address book.
She gets the error message:
Invalid address book: dcb8482afadaba3804aa38903f2bbe6f

I've no idea where the above id comes from, but it's persistent.

We have been using horde-webmail-1.2.6 for more than two years.
Other users don't have this problem.

Sources are 'localsql' and 'favourites'.
'use_shares' is set to true for 'localsql'.


Regards
Helga Mayer
