Evolution does not start anymore after an upgrade

[Erich Dollansky]

Hi,

(evolution:23621): GConf-CRITICAL **: gconf_schema_get_type: assertion `schema != NULL' failed

(evolution:23621): GConf-CRITICAL **: gconf_schema_get_default_value: assertion `schema != NULL' failed

(evolution:23621): GConf-CRITICAL **: gconf_value_new: assertion `GCONF_VALUE_TYPE_VALID(type)' failed

evolution-shell-ERROR **: Unable to create EShellSettings property for GConf key '/apps/evolution/addressbook/completion/show_address' of type 'invalid'

all I found at the Internet was this:

Should I delete the settings and try again?
