Introjucer crash (latest tip) maybe because indexOfSorted


when saving a projects

the problem that the second parameter of compare is a nullptr

Gah… It’s those template changes that Vinnie suggested for the array comparator methods. I had a nagging feeling that they might break something, but couldn’t think of an example… In fact, passing a ScopedPointer as one of the parameters is the problem, as it’ll make a temporary copy of the scopedpointer, which will clear the original. I’ll roll back that change, as this could bite other people too.
