Diff button from qcommit throws an error

[Emanuel Angelo]

From the qcommit dialog, if we press the "Diff" button the following error is thrown:

brz: ERROR: TypeError: DiffButtons._triggered[QString].emit(): argument 1 has unexpected type 'bool'

Traceback (most recent call last):
  File "/home/user/.local/lib/python3.9/site-packages/breezy/plugins/qbrz/lib/diff.py", line 170, in triggered
    self._triggered.emit(ext_diff)
TypeError: DiffButtons._triggered[QString].emit(): argument 1 has unexpected type 'bool'
