Yep. Fails here as well.

The Secret Service API allows only strings for attribute keys and
values, see 
<https://specifications.freedesktop.org/secret-service/latest/re03.html>:

--8<---------------cut here---------------start------------->8---
READWRITE Dict<String,String> Attributes ;
--8<---------------cut here---------------end--------------->8---

Looking at auth-source.el. there was a similar problem in
auth-source-plstore-search, see commit
fcb89237d9ab969bcd29bf8f8fae8d9905644b92 in Emacs git. Applying a
similar change to auth-source-secrets-search let the error go away.

I've appended the patch, could you pls check in the rcirc context? I'm
also not sure whether we need to change something when creating an item
in auth-source-secrets-create.

Best regrads, Michael.
