Re: Deep recursion error

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


takes 12 secs in 3.1.0 trunk, and consumes about 180MB of RAM alright. it
also produces lots of ugly non-fatal warnings:

Deep recursion on subroutine "Mail::SpamAssassin::Message::Node::content_summary" at lib/Mail/SpamAssassin/Message/Node.pm line 441.
Deep recursion on subroutine "Mail::SpamAssassin::Message::Node::_find_parts" at lib/Mail/SpamAssassin/Message/Node.pm line 127.
Deep recursion on subroutine "Mail::SpamAssassin::Message::Node::finish" at lib/Mail/SpamAssassin/Message/Node.pm line 640.
Deep recursion on subroutine "Mail::SpamAssassin::Message::finish" at lib/Mail/SpamAssassin/Message/Node.pm line 640.

it'd be nice to fix this -- could you open a bug on the bugzilla
and attach the message to that as an attachment?
