QtConcurrent::run() doesn't handle QtConcurrent::Exception(s)

When exception is thrown from QtConcurrent::run(), the following warning is displayed:

"Qt Concurrent has caught an exception thrown from a worker thread.
This is not supported, exceptions thrown in worker threads must be
caught before control returns to Qt Concurrent."

The exceptions could be handled in the same way as in the other QtConcurrent functions such as QtConcurrent::map.
