This is information only. I have already reported the bug through bugzilla.

Evolution version 3.4.3 under F17 has an issue when accessing the Contacts data base. After you access the Contacts data base in Evolution, the sub-process evolution-addressbook-factory is started. This sub-process never ends, even after exiting Evolution normally. The extended issue from this is the Contacts data base file created in Evolution can be corrupted, preventing the user from being able to delete or add contacts as necessary. I found I had to move the data base files under Evolution to another location and have Evolution re-create the data base from scratch.

When I exit Evolution, I manually kill the evolution-addressbook-factory process before starting Evolution again.
