Problem seems to be in the polling code; there is done

| // authentication
| ...
|    gnutls_record_recv(session)
| 
| // application data xfer
| 
|    poll(<session-fd>,...)
|    gnutls_record_recv(session)

The gnutls_record_recv() in the authentication step received more data than
expected (dovecot sends two response lines after login ('* CAPABILITY...'
and the '. OK logged in' one)). The IMAP authentication code expects only
one line and data of the second one stays in the private buffers of the TLS
session.

As this data is in the private buffers only, the following poll() won't
return and program will stop until it sees data from stdin.


Previous fedora versions had probably a gnutls or glibc version which
have smaller buffers so that this code worked.


I will provide a patch soon...
