Bug#859336: [Intent to NMU] seahorse: Sign key or edit trust results in "General Error"

[mercedes508]

Hi,

I just tried to reproduce that issue using Seahorse 3.20.0-3.1 in both
Tails 3.0-beta4 and a fresh install of Debian Stretch and got the
"General Error" when trying to sign a key.

But interestingly enough, in both setup I only get that error when
trying for the first time to sign, every signature after that first
error goes fine.

Here are logs from Seahorse:

** (seahorse:10389): CRITICAL **: egg_datetime_set_clamp_date: assertion
'minyear <= maxyear' failed

(seahorse:10389): seahorse-CRITICAL **: file
pgp/seahorse-gpgme-key-op.c: line 551 (sign_transit): should not be reached

Cheers.
