New description:

 Perl plugins that hook received-im-msg or received-chat-msg crash Pidgin
 when the incoming message triggers.

 I believe this problem relates to 64bit Linux system, as nearly identical
 32bit Linux system does not seem to crash and works fine.

 Ubuntu Linux, 2.6.24-19-generic x86_64

 Can produce in both Latest checkout of source code today 2.5.1dev and
 compiled 2.5.0.  This is from 2.5.1dev:
