Comment 3 for bug 490744

this is a reasonable error due to the fact you haven't provided in the C++ shared object the necessary symbol Demangling. As well as your maybe calling the dlopen'd function incorrectly since dlsym returns a function pointer which you call as instead of a real function. http://www.dwheeler.com/program-library/Program-Library-HOWTO/dl-libraries.html
