Hello Davide,
I can't really reproduce or completely missunderstood your report. The
presentation of the subject is the same as for email. If someone is
writing a vera long mostly useless subject there is also no line break
or scroll bar. It make absolutely no sence writing subject lines with
more than 120 characters so I say this isn't a bug.
Sorry for taking this report the long time unanswered. But it seems there
are not many people that using the RSS Feed function within Icedove and
having issues with that.
So I would like to close this report.
Regards
Carsten
