Package: libemail-mime-perl
Version: 1.925-1
Severity: normal
I see frequently this:
Use of uninitialized value $header in pattern match (m//) at
/usr/share/perl5/Email/MIME/Header.pm line 19
Use of uninitialized value $val in pattern match (m//) at
/usr/share/perl5/Email/MIME/Encode.pm line 31
I can easily reproduce the "Encode.pm line 31". The warning shows up
on headers similar to this:
To: f...@example.org, =?Windows-1252?Q?G=F6ran_Haraldsson?=
<goran.haralds...@example.org>
but not on this:
To: foo <f...@example.org>, =?Windows-1252?Q?G=F6ran_Haraldsson?=
<goran.haralds...@example.org>
^^^^^ ^
I can produce a simple example code, if needed. Still, this patch:

removes some Encode.pm warnings. I suspect the Header.pm warning has a
similar cause. What about this patch:
