Hi there, thanks for mp3tag!
importing an album from MusicBrainz, it seems a "|" (Vertical Line, U+007C in UTF-8) triggers a new line in the import script.
see linked screenshot: http://imgur.com/wNWZFeZ
I downloaded and tested with 2.54 that showed the same behaviour as the formerly used 2.49.
can I correct that flaw myself?
