I cannot reproduce your problem.

#0  magazine_chain_pop_head (mem_size=8) at gslice.c:486
486	      (*magazine_chunks)->data = chunk->next;

Thread 1 (Thread 2415):
#0  magazine_chain_pop_head (mem_size=8) at gslice.c:486
        chunk = 0xff
#1  thread_memory_magazine1_alloc (mem_size=8) at gslice.c:789
        mag = 0x9da80c0

It seems a buffer overflow is happened.
Probably I guess another problem causes this problem.

How do you reproduce your problem with reproducing steps?
Which locale do you use?
Which ibus engine do you use? pinyin?

It seems you got your problem when you try to show U+8CDE '賞' with ibus lookup table.
I don't see any problems with my Fedora 13 64bit.
