New description:

 Recently we ported our code on 64 bit and following is consistent crash in
 2.7.9 in 64 bit version. I am running it on CentOS 6. The 32 bit version
 runs fine. This is also happens when buddies have their presence status in
 non-english language for example arabic. Below is backtrace

Comment:

 Um, 2.7.9 is pretty old, 2.10.3 is current. Any reason you should be using
 this old version of libpurple?
