Hello there,

I was batch-converting some music files with k3b, ripped with cue files, and it looks like k3b fails to parse the cue file if the TITLE section is larger than 80 bytes.

For now, I ran

`LANG=C sed -i 's/TITLE\s\+"\(.\{80\}\).\+"/TITLE "\1"/' *.cue`

on my files, but this is less than ideal.

Tested with k3b 17.08.1 on Arch linux (this version doesn't appear on the bug tracker page).

k3b fails with:

(K3b::CueFileParser) unknown Cue line: ' "TITLE \"This is a title wider than 80 bytes**********************************************\"" '


What's nice is that the bug is EXTREMELY EASY to reproduce: just create a file with the following line and a .cue extension.

TITLE "This is a title wider than 80 bytes*********************************************"

Remove a star, and you instead get:
(K3b::CueFileParser) successfully parsed cue file.

I would like to see the following happening:
- Support for titles longer than 80 bytes, with unicode if possible
- If too complicated, cut the title to 80 bytes and warn the user
- If this can't be implemented because of manpower constraints, at least provide a decent error message.

I could try to do it myself, but I suspect that it will take no time to fix for someone familiar with the codebase.

Thanks for maintaining k3b,

Mayeul
