Title:
  Timout for gpg-agent related operations performed by enigmail like:
  decrypt a message

Status in gnupg2 package in Ubuntu:
  Confirmed

Bug description:
  This bug was also reported to the Bugtracker of the Enigmail Project: http://sourceforge.net/p/enigmail/bugs/540/
  As it seems to be related to Ubuntu I open this bug here:

  I am running a freshly installed Ubuntu 15.10 using GnuPG 2.0.28 and
  Thunderbird 38.3.0 using Enigmail 1.8.2.

  All operations that access the gpg-agent seem to run into a timeout
  and for this reason they are very slow. This means that signing,
  decrypting, encrypting take additional ~25 seconds in order to be
  performed.

  One specific example:

  1.    There is an encrypted email in my inbox and I select these email.
  2.   The message body is shown as encrypted text block
  3.    I am waiting ~ 25 seconds
  4.    I am asked to enter the password for the key used to decrypt the message
  5.    Entering the password
  6.    The message is shown in plain text.

  This behaviour is exactely the same if I jump to another unencrypted
  email in my inbox and afterwards back to the encrypted one.

  There seems to be a timeout with the gpg-agent because the Enigmail
  log says for the example above:

  Initializing Enigmail service ...
  EnigmailAgentPath=/usr/bin/gpg2

  enigmail> /usr/bin/gpg2 --version --version --batch --no-tty --charset utf-8 --display-charset utf-8
