Linking with purple-based (skype) contact fails

[wvengen]

I have an MSN account and a purple-based pidgin-skype account. Contacts of both appear in my contact list. When I link two MSN contacts, it works as expected. When I link a Skype contact (either with an MSN or another Skype contact), nothing happens after selecting the contacts to link. In my ~/.xsession-errors the following message is given:
  (empathy:26316): libebook-CRITICAL **: e_contact_set_attributes: assertion `field_id >= 1 && field_id <= E_CONTACT_FIELD_LAST' failed
I had expected the contacts to become linked.

Ubuntu 11.10 / empathy 3.2.0-0ubuntu1 / libpurple0 1:2.10.0-0ubuntu2 / pidgin-skype 20110407+svn612+dfsg-1ubuntu1

Status changed to 'Confirmed' because the bug affects multiple users.

I've marked folks as affected too because it also doesn't work if the linking is made via gnome-contacts.
