I have noticed some inconsistency in the name of the contacts. In the contact list in the left and the title in the top screen is ok, but in the chat, I see the xmpp address instead of the contact name.
I remember I renamed this contact and maybe he doesn't set his name on his profile.
I always connect to converse.js like an untrusted device and I always remove cookies when I close the browser, so it is like if always is the first time I enter the application.

There isn't enough information here in order to write a test that reproduces the bug, so that it can be fixed.
If you can reliably reproduce this bug, perhaps you can send me the stanzas of that session?
@jcbrand, I sent you the info in private.
Thanks.
I think it is fixed in 5.0.1.
Thanks.
