If the code is behaving strangely, take a look in the `debug.log` file in the data directory;
error and debugging messages are written there.
The `-debug=...` command-line option controls debugging; running with just `-debug` or `-debug=1` will turn
on all categories (and give you a very large `debug.log` file).
Debug logging can be enabled on startup with the `-debug` and `-loglevel`
configuration options and toggled while bitcoind is running with the `logging`
RPC. For instance, launching bitcoind with `-debug` or `-debug=1` will turn on
all log categories and `-loglevel=trace` will turn on all log severity levels.
The Qt code routes `qDebug()` output to `debug.log` under category "qt": run with `-debug=qt`
to see it.
