Hi,

please have a look at the attached patch which prevents adding accounts more 

than once. Currently kopete crashes when doing that, the patch modifies most 

plugins such that a friendly message pops up when creating a duplicate 

account in the add account wizard and proceeding to the next page is not 

possible. Additionally, the accept() method of the wizard does that check 

again (e.g. the Testbed protocol doesn't have the duplicate check).

If there are no objections, I'll check it in.

Regards,

Dennis
