Today I am wearing my Debian Developer hat. Some longstanding Perl warnings in mhonarc have finally graduated into failure. There is a patch that appears to fix the problem.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816638 https://rt.cpan.org/Public/Bug/Display.html?id=76857 I'm planning to update the Debian package with this fix, some time over the next few days. No action required on behalf of MHonArc. However, MHonArc may want to think about cutting a 2.6.20 release containing this patch. I expect most Linux distributions to start having this problem over the next year, if they aren't already. Jeff
