[Pkg-mozext-maintainers] Bug#847054: enigmail: keeps imap connections open

[IOhannes m zmölnig (Debian/GNU)]

Package: enigmail
Version: 2:1.9.6-2
Severity: normal

Dear Maintainer,

for a while, 'icedove' has tried to tell me that my user-password on one of my
imap-accounts is invalid.
Checking the imap server logs, it seeems that the account has exhausted its
"maximum allowed connections per IP" (and thus the imap-server refuses any new
connection attempts from my client).
Restarting 'icedove' did *not* really help, so i checked what is eating up all
my connections, and it turned out to be: gpg2!

Because the processes are coupled with an imaps connection, i have a strong
suspicion that the actual culprit is enigmail (which is the only piece of
software that could possibly associate my imap-accounts from icedove with gpg2).

Some of the gpg2 processes that keep a connection alive are quite long-lived,
e.g. as of today (Dec.5), i have one that started on Nov.22

as an additional data point, i'm experiencing random crashes of icedove. while
this might be unrelated to enigmail, these might be the reason why the forked
gpg2 processes do not get cleaned up...
