[evolution-data-server/openismus-work-error-args: 2/2] libebook: Report missing phone number support by GError



commit b6b7263803ed39d9f6a2835da6b100a85f8e0f38
Author: Mathias Hasselmann <mathias openismus com>
Date:   Thu Mar 7 13:25:01 2013 +0100

    libebook: Report missing phone number support by GError
    
    Add GError arguments to e_phone_number_get_default_region() and
    e_phone_number_get_country_code_for_region() to properly report
    missing phone number: Warnings cannot be handled programatically
    and make GTest based unit tests failed.
