Courier::Filter 0.17 fixes some bugs with badly encoded characters 
causing it to crash. However, there's still one left.

Starting a few days ago, Courier::Filter on my system is crashing, with 
the following sequence of events:

Nov 25 00:37:46 werkt courieresmtpd: MAIL FROM: 
<[EMAIL PROTECTED]>
Nov 25 00:37:46 werkt courierfilter: Wide character in subroutine entry 
at /usr/share/courier-filter-perl/perl5/Courier/Message.pm line 625.
Nov 25 00:37:46 werkt submit: No such file or directory
Nov 25 00:37:46 werkt submit: Connection reset by peer
Nov 25 00:37:46 werkt last message repeated 2 times
Nov 25 00:37:46 werkt courieresmtpd: 
error,relay=::ffff:217.167.242.138,from=<>: 432 Mail filters temporarily 
unavailable.
Nov 25 00:37:46 werkt submit: Connection reset by peer
Nov 25 00:37:46 werkt last message repeated 2 times

The mailserver this runs on is busy enough that it's impossible to tell 
which of these messages are from the same session, but I think the 
important ones are

Nov 25 00:37:46 werkt courierfilter: Wide character in subroutine entry 
at /usr/share/courier-filter-perl/perl5/Courier/Message.pm line 625.
Nov 25 00:37:46 werkt submit: No such file or directory

and the subsequent

Nov 25 00:37:46 werkt courieresmtpd: 
error,relay=::ffff:217.167.242.138,from=<>: 432 Mail filters temporarily 
unavailable.

... because when this happens the running pureperlfilter process goes dead.

The offending line 625 in Courier::Message seems to be enclosed in a 
try/except block that it seems to me should catch this problem, but I'm 
not familiar enough with Perl or character-encodings to determine if it 
is. I'm also curious if (or why) I'm the only user of Courier::Filter 
seeing this. Perhaps it's a problem with my installation/perl version?

I'm using

courier-0.53.3-1.3
perl-5.8.5-24.FC3
Courier::Filter 0.17

(on Fedora Core 3).

Thanks!
