Comment 3 for bug 330454

I had the same issue with pidgin:

% pidgin
error: duplicate REP tables used
Failure loading aff file /usr/share/myspell/dicts/en_ZA.aff
zsh: segmentation fault pidgin

But in my case it was related to the facebook plugin:

% dmesg | tail
[ 309.408258] pidgin[5288]: segfault at 28 ip 00007f9c8090c952 sp 00007fffa490a390 error 4 in libfacebook.so[7f9c80908000+c000]

Removing the pidgin-facebookchat package resolved my problem for the moment.
