It's a null pointer in a C library. Somewhere in the stack, you are calling something, which calls something, which eventually calls into the library. Look carefully at all the parameters that you are using on that chain of calls. Mostly likely, one of them is wrong, causing the library to barf.

Check all return values, too. Bit surprised to see that the library has not been stripped of symbols.
