>Description:
The past several port revs of both net-im/pidgin and security/pidgin-encryption have come together to create a problem where if you run pidgin and attempt to enable the pidgin-encryption module, it immediately cores.

Because pidgin is a threaded app, the backtraces I've obtained don't appear to be very useful, but here's what I got:

Here's some of the relevant port versions I have installed as the problem stands:

pidgin-2.2.2
pidgin-encryption-3.0_2
libpurple-2.2.2
nss-3.11.7
libiconv-1.11_1

I've insured that other modules can be loaded properly, as well as eliminating environmental issues by reproducing the problem with a test account with a clean home directory.
>How-To-Repeat:
Launch pidgin, select tools - plugins, locate 'Pidgin-Encryption 3.0' in the dialog box, then click the check-box next to it.  pidgin will immediately core.
