A guess at what happened - you had mutt (compiled against gnutls3) and
gnutls3 installed. You use imap:// rather than imaps:// (i.e.
opportunistic STARTTLS). Mutt didn't work.
You then installed libgnutls4 and removed gnutls3. Mutt no longer could
load the gnutls module so didn't use TLS. Mutt worked.
You then upgraded to a version of mutt which uses gnutls4. Mutt could
use the gnutls module and broke again.
(As an aside this reminds me about a bug I've reported on mutt-dev but
I ought to file in upstream's BTS - you can't rely on the current
opportunistic STARTTLS behaviour to give you TLS in the presence of an
Anyway, the bug itself - it looks like it is in libgnutls itself, or
maybe libgcrypt. I'm forwarding this to the gnutls-dev for thoughts.
Can you also confirm which version of the Debian gnutls4 or libgnutls4
package you are using?
