Weird Characters in unexpunge

[steffo76 at gmx.de]

Hello all,
 
unexpunge (cyrus 2.5.7) is showing weird behaviour when it comes to subject lines containing the double quotation mark ("). When running reconstruct -l the subject lines containg a '"' show up as
 
{<Number>}<Line Break>Subject, for instance

        Subj: {109}
Cron <root at machine>
 
I redirected the output to a file and opened it with vim, which shows a ^M before end of the line, which is a carriage return if I'm not mistaken. So I guess there is a <CR><LF> involved.

The mail as such looks perfectly fine. Is this a feature or should I open a bug report ?
 
Thanks,
Stephan
