Dear Maintainer,

Testing https://delta.chat/ on Debian Buster, I noticed IMAP connection
failures. After some debugging, I have tracked it down to a problem in upstream
libetpan when built against a new-enough GnuTLS. PR for that here:

https://github.com/dinhviethoa/libetpan/pull/330

The outcome of this bug is that SSL negotiation timeouts are 1,000 times less
than they should be - Delta's 10 second timeout becomes 10ms. The default 30
second timeout becomes 30ms, which might *just* be long enough in some cases,
but certainly not all.

I'm opening a Debian bug report as I'd like the fix to be included in Debian
Buster. Otherwise, all software that uses libetpan (including Claws email, I
believe) will fail to negotiate TLS in seemingly-random circumstances. It's a
one-line fix, the consequences of which are very easy to understand.
