As I submitted a bug report before but it turned out to be a Gaim issue. So i reported to the Gaim bug support and got a fix for this crash with QQ protocol. It turns out that "qq_send_packet_get_buddies_levels(gc)" needs to be commented out in "/var/tmp/portage/gaim-2.0.0_beta6/work/gaim-2.0.0beta6/libgaim/protocols/qq/buddy_list.c" I applied this fix and it worked for me. The fixed buddy_list.c is attached.
