Package: mutt
Version: 1.5.21-6.2
Severity: important

Dear Maintainer,

I have:

    set smtp_authenticators = 'gssapi'

and when the authentication fails, mutt will sometimes say "No authenticators
available" in its bottom row, and never return control to the user.  An example
reason for the authentication failing is that the tgt has expired.  The bug
doesn't happen every time.  Sometimes the error message will be displayed and
control returned to the user.  For me at the moment, it's around 3 in 4 times
that the bug is seen when the conditions are as described above.

When a similar situation occurs with imap_authenticators, it displays the same
error message, but seems to always nicely return control to the user instead of
hanging.

As a workaround, an additional mechanism can be added.  Even if there is no
intention of using the other mechanism, it seems to allow control to pass more
reliably back to the user.  For example:

    set smtp_authenticators = 'gssapi:login'
