[pkg-gnupg-maint] Bug#800032: pinentry-gnome3: Pinentry hangs for ~30s before asking for passphrase when invoked by Enigmail

[Ondřej Kuzník]

Package: pinentry-gnome3
Version: 0.9.5-4
Severity: important

Dear Maintainer,
recent upgrades to either enigmail, gpg or pinentry have started to take
a long time to ask for the passphrase on sending/decrypting an email.
Stracing the gpg-agent daemon looks like pinentry is launched, it
creates a process/thread(?) which doesn't seem to do much, just waits on
a futex for 15 seconds, then times out and then another similar
process/thread is cloned doing essentially the same thing. Only then
after the second timeout does it display the prompt. This happens with
pinentry-gtk2 as well. I can provide a slightly cleared up strace if
that would help.

Does not seem to happen with gpg/mutt/others, but given that the process
that waits for too long is part of pinentry, I report here.

The desktop environment is Fluxbox with gnome-settings-daemon running.

Thanks,
Ondrej
