Thunderbird/Enigmail problem

[Jan Danielsson <jan.m.danielsson%gmail.com@localhost>]

Hello,

   I just built Thunderbird (from pkgsrc-current) on NetBSD/amd64 6
beta. When I try to do anything with Enigmail I get an error. The
enigmail debug log says:

---------------------
[---]
2012-04-03 12:51:15.725 [CONSOLE] EnigmailAgentPath=/usr/pkg/bin/gpg

2012-04-03 12:51:15.725 [DEBUG] enigmail.js: Enigmail.setAgentPath:
calling subprocess with '/usr/pkg/bin/gpg'
2012-04-03 12:51:15.726 [ERROR] enigmail.js: Enigmail.setAgentPath:
subprocess.call failed with 'TypeError:
platformDefaults[gXulRuntime.OS.toLowerCase()] is undefined'
[---]
---------------------

   The problem appears to be spelled out in plain text:

   ``platformDefaults[gXulRuntime.OS.toLowerCase()] is undefined''

   Is it Enigmail's fault for assuming too much, or is it Thunderbird's
fault for missing expected features?
