I asked this before for the same error (in different software), and
christos explained:

--- begin quote ---
It is calling pthread_setspecific() for a key where pthread_key_create()
has not been called:

     Undefined behavior may follow if either function is called with a key
     value not obtained from pthread_key_create(3), or if the call is made
     after key has been deleted with pthread_key_delete(3).
--- end quote ---

I think this might due to cleanup functions called in incorrect order
(e.g. shared library unloading).
