[Dovecot] Incomplete Subject Line

[Bernhard Schmidt]

Hi,

since upgrading from 1.0.5 to latest 1.1-hg I get an incomplete subject
line for mails autogenerated by one of our systems in the message list
(Thunderbird and mutt). When I open the mail the subject line is intact.

It appears that the system is using multiline subjects. Example

Subject: =?ISO-8859-1?B?SG9zdG1hc3RlcjogMDAwMDEwNjM1OiBOYW1lc2U=?=
 =?ISO-8859-1?B?cnZlcjogTmV1dmVyZ2FiZSBvZGVyIMRuZGVydW5n?=

is printed as

Subject: Hostmaster: 000010635: Namese

in the Message list and correctly decoded as

Subject: Hostmaster: 000010635: Nameserver: Neuvergabe oder Änderung

when viewing the message.

Bug?

Regards,
Bernhard
