cCutter::Active is more than a simple query function. It also does the 
cleanup of the thread, the error handling and the external script calls. 
Because of that, the function is not thread safe, and can only be called 
from the main thread. The double free is probably because both threads 
try to free cCutter::editedVersionName at the same time.
