Hi Tomas Liljebergh,
I tried to replicate the issue and i faced no such problem on creating Federation/Aggregate Trust relationship in my environment.
> You can find the metadata at: https://mds.swamid.se/md/swamid-sp-transative.xml That is the URI we are using in our 4.1.1 installation and there it works well with thousends of succeded logins everyday.

i tried your metadata url as well to create trust relationship, which led to incative trust relationship. as suggestion please try a different metadata url to add a trust relationship and inform us if you get the same result.
Thanks and regards
Mohit Mali.
