[pkg-gnupg-maint] Bug#790316: pinentry-gnome3: sometimes refuses to provide passphrase to agent

[brian m. carlson]

Package: pinentry-gnome3
Version: 0.9.4-2
Severity: normal

From time to time, pinentry-gnome3 refuses to provide the passphrase
stored in gnome-keyring to the agent.  An abbreviated transcript of the
session follows (from gpg --debug-all -b FILE):

  gpg: DBG: get_keygrip for public key
  gpg: DBG: keygrip= 37 EC 57 47 4F 5B 89 4C 24 CD AA 87 B2 10 FF 4F 43 19 77 92
  gpg: DBG: chan_5 -> RESET
  gpg: DBG: chan_5 <- OK
  gpg: DBG: chan_5 -> SIGKEY 37EC57474F5B894C24CDAA87B210FF4F43197792
  gpg: DBG: chan_5 <- OK
  gpg: DBG: chan_5 -> SETKEYDESC Please+enter+the+passphrase+to+unlock+the+OpenPGP+secret+key:%0A%22brian+m.+carlson+<sandals at crustytoothpaste.net>%22%0A4096-bit+RSA+key,+ID+1F52F68B,%0Acreated+2007-05-14(ID+de+clave+primaria+0223B187).%0A

  gpg: DBG: chan_5 <- OK
  gpg: DBG: chan_5 -> PKSIGN
  gpg: DBG: chan_5 <- INQUIRE PINENTRY_LAUNCHED 44889
  gpg: DBG: chan_5 -> END
  gpg: DBG: chan_5 <- ERR 83886179 Operation cancelled <Pinentry>
  gpg: firma fallida: Operation cancelled

All of the keychains are unlocked (as can be viewed in seahorse), and I
can view that there's a passphrase for keygrip
n/37EC57474F5B894C24CDAA87B210FF4F43197792, but the pinentry cancels the
operation.  Once the operation fails, it fails until I kill gpg-agent
(and a new one is respawned).  However, killing the gpg-agent is always
effective at fixing the problem.

No window appears during the signing attempt, whether it is successful
or unsuccessful.
