I finally found out, why I wasn't able to login after registration. I use a password safe utility that pastes in a generated password. As there was this know issue at isaacs read, I took a deeper look in the dependency tree and figured out the problem:
¬ firstname.lastname@example.org ¬ email@example.com ¬ firstname.lastname@example.org - email@example.com
So, as prompt inside flatiron is used for reading from stdin, there it is. I took a look at the flatiron repo and the newest version there is 0.2.8 now:
¬ firstname.lastname@example.org ¬ email@example.com - firstname.lastname@example.org
Aha! So I updated to flatiron 0.2.8 and now I can paste in my password :)
This pull request passes (merged 42ebec4 into 02ec4ab).
+1 Good catch.
I did not realize that the copy / paste bug had already been fixed in read. Same thing happened to me.
