EML flag gives only errors

[Disonantemus]

Today I found out that reader can work with EML files, then I tried the --eml flag with some emails, and ... from 20 eml files, 20 (all) gives errors, none was shown as expected.

Using mbox2eml

I did convert a mbox file to many eml files (Spanish emails):

mbox2eml < in.mbox

The output from 16 (from 20) files was similar to:

reader --eml in.eml
message: malformed MIME header key: From "user123456@notarealemail.com" Fri Mar 13 11

Same files was able to be shown not using --eml flag

Output from 4 (from 20) files:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0xd2c6ab]

Using mboxshell

i did open the same mbox file and extract some eml files with export option, and get:

reader --eml in.eml
unknown charset: unknown charset: message: unhandled charset "windows-1252"

The same file was able to be shown with reader, when it's not used the --eml flag.

Hey there, would it be possible for you to share one example .eml file?
