Hello,

adding the Debian Perl Group to Cc, maybe they can help here.
(for context look at https://bugs.debian.org/1002219)

I can reproduce this problem with 1.6.1 checked out. I played a bit 
around (suffering from my weak perl foo) and found that when I downgrade 
libemail-mime-perl from 1.952-1 (i.e. Debian unstable's version) to 
1.949-1 (i.e. Debian stable's version), this works.

The reproducer is:

$ perl -e 'use Email::MIME; print Email::MIME->new("Content-Type: 
text/x-patch; 
name=\"=?utf-8?q?vtpm-fakefile.patch?=\"\nContent-Disposition: 
attachment; filename=\"=?utf-8?q?vtpm-makefile.patch?=\"\n\n")->filename;'

which emits "vtpm-makefile.patch" with 1.949-1 (as public-inbox 
expects), but =?utf-8?q?vtpm-makefile.patch?= with 1.952-1.

So the key question is: Is the test correct and his is a regression in 
libemail-mime-perl, or is the test wrong and we need to fix the test 
(and PublicInbox::Eml)?

Best regards
Uwe
