You can get a debug log by using:

Preferences -> Restart in debug mode

It will create a text file containing the debug log, IIRC.

I did the porting using modernize now. Got better results:

1) ACE ported almost flawlessly. It works fine but for one error in the config dialog:

a) OPEN FOLDER. This gives the same error reported by @JimmXinu.

Spoiler:

calibre, version 4.99.0

2) Skoob Sync had more problems. First I had a problem with encoding a password with base64 (which I ended up giving up). There were a lot of other errors about encode/decode of strings/bytes with urllib requests.
Right now, it is working partially. Some functions work, others make calibre hang. Trying to debug now...

______________________________
EDIT: Looks like the problem is on my multi-threading code. Until now (4.6), sometimes I got an error like this:

QObject::setParent: Cannot set parent, new parent is in a different thread

But it did not prevent the plugin to run. Now, every time this error shows up, calibre hangs. Apparently, python 3 is more error intolerant ....

This is my code for multi-threading:

Spoiler:

    def run_parallel_in_threads(self, target, args_list):
        ''' Utility - spawn a thread to execute target for each args '''

        result = six.moves.queue.Queue()

        # Wrapper to collect return value in a Queue
        def task_wrapper(*args):
            result.put(target(*args))

        threads = [threading.Thread(target=task_wrapper, args=args) for args in args_list]

        count = 0

        for t in threads:
            count += 1
            t.start()
            # Don't send all requests at once
            list_size = len(args_list)
            if (list_size - 20) > 10:
                if count == 20:
                    time.sleep(1)
                elif count == 30:
                    time.sleep(1)
                elif count == 40:
                    time.sleep(2)
            elif (list_size - 20) > 0:
                if count == 20:
                    time.sleep(1)
            time.sleep(0.1)
            QApplication.processEvents(QtCore.QEventLoop.ExcludeUserInputEvents)
        for t in threads:
            t.join()
        return result

Anyway... I will keep digging.
