The above looks suspicious. The cast you're doing here is unsafe. Your
check on base on the second line is useless, as the C-style cast you're
using doesn't do any checking. So, my suspicion is that your item isn't
a BaseObject, and thus the method call you make into it is going to
fail. Use a dynamic_cast<BaseObject*>(item) for your cast instead. That
cast _ will_ result in a 0 pointer if the cast fails.
