seems to be the same issue as bug 504795. I cooked up a patch for my issue, I smell other bugs, because *every* functions array has to be NULL terminated (with the solution I propose).

Patch which checks for the end of an NULL terminated(!) array
This fixes the issue for me. If you want to port this patch to fix other issues, look out for the creation of a char* array which is passed to FunctionBar_new. The array has to be NULL terminated.

Patch which NULL terminates all arrays
This patch NULL terminates all arrays, I've found.
